report-editor

Original：🇺🇸 English

Translated

Use when modifying EXISTING Datex Studio reports on a branch. Handles label/style changes, field rearrangement, adding/removing columns, datasource modifications, and adding new data sections. Trigger for: "edit a report", "modify a report", "change the label", "add a column", "update the report on branch X", "fix the report layout". For creating NEW reports from scratch, use `report-creator`.

Report Editor

Workflow for modifying existing RDLX-JSON reports on a Datex Studio branch using the

dxs

CLI.

Key principle: Understand before modifying. Download and inspect the current report before making any changes.

Authoring approach:

Incremental CLI (

set

move

remove

batch

table add-column

dataset add-field

) for all modifications

Direct JSON only for structures the CLI cannot handle (PageHeader/PageFooter, complex Tablix grouping)
Never recreate from scratch -- work with the existing file

  |     +-- Cat 1-2: Layout-only --> set/move/remove/batch on folder/report.rdlx-json
  |     +-- Cat 3: Add from existing DataSet field --> table add-column
  |     +-- Cat 4: Datasource gap --> datasource-creator --> datasource add --> DataSet --> layout
  |     +-- Cat 5: New section --> schema-explorer --> datasource-creator --> datasource add --> DataSet --> layout
  |
  +-- Phase 4: Deploy & Verify (deploy-patterns.md)
  |     +-- assemble folder --> wrapper JSON
  |     +-- upload wrapper JSON

Phase 1: Download & Inspect

Select branch and find report

Follow branch-setup.md for branch/connection selection.

Then list reports on the branch:

bash

dxs report list --branch <branch_id>

Present reports to the user if the target is ambiguous. If the user named a specific report, match it against the list.

Download the report folder

bash

# Auto-names folder from reference name
dxs report download --branch <branch_id> --reference-name <reference_name>

# Or specify folder path explicitly
dxs report download <folder_path> --branch <branch_id> --reference-name <reference_name>

This creates a report folder containing:

```
report.rdlx-json
```
-- the RDLX-JSON layout (editing commands target this)
```
manifest.json
```
-- all binding metadata (datasources, params, datasource-params, access modifier)
```
ds_*.json
```
-- one file per owned datasource config (extracted from the wrapper)

The manifest preserves all datasource bindings, parameter mappings, and metadata. No manual extraction or flag reconstruction needed for re-upload.

Inspect the report folder

Check the manifest to understand datasource bindings:

bash

dxs report datasource list <folder>/

Inspect the layout:

bash

dxs report inspect <folder>/report.rdlx-json

Also read the RDLX-JSON directly to understand DataSets, element hierarchy, and expressions.

Visual layout inspection

Use

--bbox

to generate a preview with colored bounding boxes — helpful for understanding element positions before modifying:

bash

dxs report preview <file.rdlx-json> --bbox ElementName:red --bbox AnotherElement:blue -o /tmp/inspect.svg

Inspect current layout

bash

dxs report inspect <file.rdlx-json>

This shows every element with type, name, position, size, value/expression, and DataSet bindings. Also read the file directly to understand:

DataSets (names, fields, CommandText patterns)
Element hierarchy (rectangles containing children)
Expressions used
Page settings (size, margins, orientation)

Identify available datasource fields

For EACH datasource used by the report (check

dxs report datasource list <folder>/

to see them):

bash

# For standalone datasources
dxs report datasource-fields <datasource_ref> --branch <branch_id>

# For owned datasources
dxs report datasource-fields <datasource_ref> --branch <branch_id> --report <report_ref>

This gives you the complete field list,

in_params

, result type, and collections. This is the triage gate -- in Phase 2, you will check whether requested fields are already available here.

Report not found

dxs report list

does not return the target report:

Inform the user: "That report was not found on branch X."
Ask: "Would you like to create it from scratch?"
If yes, invoke the
```
report-creator
```
skill.

Phase 2: Triage -- Determine Change Depth

Classify each requested change into one of five categories. Different categories require different workflows.

Change Categories

Category	Examples	What's Needed	Dependency Skills
1. Label/Style	"Change 'SHIPPER' to 'FROM'", "Make header blue", "Increase font size"	`set` / `batch` only	None
2. Rearrangement	"Swap columns 2 and 3", "Move address block down", "Remove the footer"	`move` / `remove` / `set`	None
3. Add column (field in DataSet)	"Add the Status column" where Status IS in the DataSet	`table add-column` + layout	None
4a. Add field (in datasource, missing from DataSet)	"Add Material Description" where the field IS in the datasource output but NOT in the DataSet	`dataset add-field` + layout	None
4b. Add field (datasource gap)	"Add Material Description" where the field is NOT in the datasource `$select` / `$expand`	Datasource regeneration + `dataset add-field` + layout	`datasource-creator`
5. New data section	"Add a line items table" where no suitable datasource exists	Full: `schema-explorer` + `datasource-creator` + DataSet + layout	`schema-explorer` + `datasource-creator`

Decision Tree

User request
  |
  +-- Does the change involve data fields?
  |   +-- NO --> Is it positional/structural (move, swap, remove)?
  |   |   +-- YES --> Category 2 (rearrangement)
  |   |   +-- NO  --> Category 1 (label/style)
  |   |         --> Proceed to Phase 3
  |   |
  |   +-- YES --> Does the needed field exist in a report DataSet?
  |       +-- YES --> Category 3 (add column/element from existing DataSet field)
  |       |         --> Proceed to Phase 3
  |       |
  |       +-- NO --> Is the field in the datasource output? (from datasource-fields)
  |           +-- YES --> Category 4a (field in datasource, missing from DataSet)
  |           |         --> Add to DataSet, then layout
  |           |
  |           +-- NO --> Is the field reachable from the datasource's entity?
  |               |     (just missing from $select/$expand)
  |               |
  |               +-- YES --> Category 4b (datasource needs regeneration)
  |               |         --> Modify datasource --> re-upsert --> DataSet --> layout
  |               |
  |               +-- NO --> Category 5 (entirely new data requirement)
  |                         --> schema-explorer --> datasource-creator --> DataSet --> layout

Present the triage result

<HARD-GATE> Before proceeding to Phase 3, present the classification to the user and get approval. Do NOT start modifying the report without user confirmation of the plan. </HARD-GATE>

### Modification Plan

**Requested change:** [user's request]
**Category:** [1-5] -- [description]

**Steps:**
1. [what will happen]
2. [what will happen]
...

**Impact:** [layout-only / DataSet change / datasource modification / new datasource]

Proceed?

Phase 3: Modify

Open in Studio for live preview

For ANY change that involves layout (Categories 1-3, or layout portions of Categories 4-5), ensure Studio is running and the report is open for live preview BEFORE making modifications.

Auto-manage Studio per ../shared/studio-management.md: check status, start in background if needed (with readiness verification), open the report, and clean up after Phase 4.

Category 1-2: Layout-only changes

Use CLI commands per cli-commands.md:

bash

# Change a label
dxs report set <file> ElementName --value "New Label Text"

# Change styling
dxs report set <file> ElementName --font-size 12pt --color Navy --font-weight Bold

# Move an element
dxs report move <file> ElementName --left 1in --top 2in

# Resize an element
dxs report set <file> ElementName --width 3in --height 1in

# Remove an element
dxs report remove <file> ElementName

# Batch operations (for multiple changes)
cat > /tmp/ops.json << 'OPEOF'
[
  {"action": "set", "name": "Title", "value": "New Title", "font-size": "18pt"},
  {"action": "set", "name": "SubTitle", "color": "DimGray"},
  {"action": "move", "name": "AddressBlock", "left": "0in", "top": "1.5in"},
  {"action": "remove", "name": "OldElement"}
]
OPEOF

dxs report batch <file> --ops-file /tmp/ops.json

Batch limit: maximum 25 operations per call. If you have more than 25 operations, split them into multiple batch calls. Group logically (e.g., first batch for repositioning, second for styling and new elements).

Apply design-standards.md for any new or modified elements: Arial font family, official color palette, 0.25in grid alignment.

Lines require special handling. Lines use

StartPoint

EndPoint

with

start-x

start-y

end-x

end-y

-- NOT

left

top

width

height

. The

move

command does not work on lines. Edit line positions in JSON directly or use batch

set

with endpoint flags.

Category 3: Add column from existing DataSet field

The field already exists in a DataSet -- just add the column to the table:

bash

dxs report table add-column <file> --table <TablixName> --shrink \
  --header-cell "New Header" \
  --detail-cell '=Fields!ExistingField.Value' \
  --header-style 'font-family:Arial;font-size:10pt;font-weight:Bold;border-bottom-width:1.5pt;border-bottom-style:Solid;border-bottom-color:#5B08B2;padding:2pt;vertical-align:Bottom' \
  --detail-style 'font-family:Arial;font-size:10pt;padding:2pt;vertical-align:Middle;border-bottom-width:0.25pt;border-bottom-style:Solid;border-bottom-color:LightGray'

The

--shrink

flag proportionally reduces existing column widths to make room for the new column while keeping total table width unchanged.

For non-table elements (standalone textboxes), use

dxs report batch

with an

add

action to place the new field in the layout.

Apply Datex design standards for the new column -- match the styling of existing columns in the table.

Category 4a: Field in datasource, missing from DataSet

The field is available in the datasource output but was not included in the report's DataSet definition. Add it:

bash

dxs report dataset add-field <file> --dataset <DataSetName> --field "New.Field.Path"

Follow dataset-rules.md for:

Date annotations: append
```
[Date|YYYY-MM-DDTHH:mm:ss.fffffff]
```
to date fields
Collection handling: collection fields cannot be added as flat DataSet fields on a single-result DataSet
CommandText: verify the DataSet's CommandText pattern is correct for the result type

Then add the layout element (column or textbox) referencing the new field. If the report has a companion

.data.json

, update it with sample values for the new field.

Category 4b: Datasource needs regeneration

The field exists on the OData entity but is not in the datasource's

$select

$expand

. The datasource config must be updated.

For standalone OData datasources:

Get the current datasource config:
```
dxs datasource get <ref> --branch <id>
```
Identify the missing field path (e.g., needs
```
Material/Description
```
in
```
$expand
```
)
Invoke
```
datasource-creator
```
to regenerate with the updated query
```
dxs datasource upsert
```
to update the branch
Add field to DataSet with
```
dxs report dataset add-field
```
Add the layout element

For owned OData datasources:

The current config is already in the report folder (extracted during download as
```
ds_*.json
```
)
Invoke
```
datasource-creator
```
to regenerate with the updated query

Replace in folder:

dxs report datasource remove <folder> <alias>

then

dxs report datasource add <folder> --owned <new_ds.json>:<alias>

Add field to DataSet with
```
dxs report dataset add-field
```
Add the layout element

For flow datasources:

Check if the needed field is in one of the flow's source OData datasources
If yes: update the flow code to include the field in the return type, update the type definition YAML
If no: may need to update the source OData datasource first, then the flow code
Regenerate with
```
dxs datasource generate-flow
```
Re-upsert (standalone) or replace in folder:
```
dxs report datasource remove/add
```
(owned)
Add field to DataSet + layout

Category 5: New data section

A new section requires data from an entity or relationship not covered by any existing datasource.

Gather requirements for the new section (what data, what layout). A brief conversation usually suffices -- only invoke
```
requirements-gathering
```
if the section is complex.
Invoke
schema-explorer
to find the right OData entity and fields
Invoke
datasource-creator
to create the datasource config, then
```
dxs report datasource add <folder> --owned <file>:<alias>
```
(owned preferred, standalone if shared)
Add DataSet per dataset-rules.md -- use the field summary from datasource-creator as the primary source for field names, include ALL fields
Build layout (rectangle container, textboxes, or tablix) using
```
dxs report batch
```
Create/update sample data per sample-data.md if needed for preview

For DataSet creation:

bash

dxs report dataset add <file> --name ds_new_section \
  --field Id --field LookupCode --field Status \
  --field "Account.Name" \
  --field "OrderDate[Date|YYYY-MM-DDTHH:mm:ss.fffffff]"

For building the layout section, use a rectangle container for grouping:

bash

cat > /tmp/new-section-ops.json << 'OPEOF'
[
  {"action": "add", "type": "rectangle", "name": "NewSectionBox",
   "left": "0in", "top": "4in", "width": "7.5in", "height": "2in"},
  {"action": "add", "type": "textbox", "name": "NewSectionTitle",
   "parent": "NewSectionBox", "left": "0in", "top": "0in",
   "width": "7.5in", "height": "0.3in",
   "value": "Section Title", "font-size": "14pt", "color": "DimGray"}
]
OPEOF

dxs report batch <file> --ops-file /tmp/new-section-ops.json

For tables, use

dxs report add tablix

-- see cli-commands.md for full syntax including grouping, footer rows, and sort expressions.

Feedback iteration

After each modification, ask the user how it looks in Studio. Use

set

move

remove

for adjustments. Repeat until approved.

<HARD-GATE> Do NOT proceed to Phase 4 (assemble/upload) until the user has confirmed the layout looks good in Studio. Ask explicitly: "How does it look in Studio? Ready to upload, or any adjustments needed?" </HARD-GATE>

Phase 4: Deploy & Verify

Assemble and upload

The report folder already has everything needed — the manifest preserves all datasource bindings, parameters, and metadata from the download. No flag reconstruction needed.

bash

# Assemble folder into wrapper JSON
dxs report assemble <folder>/ -o <reference_name>.json

# Upload wrapper to branch
dxs report upload <reference_name>.json --branch <branch_id>

If you added or removed datasources during Phase 3, those changes are already reflected in the manifest via

dxs report datasource add/remove

Follow deploy-patterns.md for additional upload patterns and verification.

Verify

bash

dxs report get <reference_name> --branch <branch_id>

Confirm the report is on the branch with the expected structure, datasource bindings, and parameters.

Test parameter discovery

If the datasource has

in_params

, follow deploy-patterns.md to discover real test values and output them as JSON for the user to test in Studio.

Troubleshooting

See troubleshooting.md for common RDLX-JSON expression issues and layout/CLI mistakes.

Editor-Specific Issues

Mistake	Fix
Modifying report without downloading first	Always `dxs report download` to get the current version -- editing a stale local file loses other changes
Adding a field to DataSet but not updating sample data	Studio preview shows blank for the new field -- update `.data.json` with sample values
Assuming the datasource has the field without checking	Always run `datasource-fields` to verify -- the field may not be in the `$select`
Changing a field expression but not the DataSet field	If you rename a DataField path, the DataSet field must also be updated to match
Removing a datasource field that is still referenced	Check all expressions in the report for `Fields!RemovedField.Value` before removing
Adding collection-path fields as flat DataSet fields	Collection navigation properties silently resolve to blank in single-result DataSets -- use a flow datasource to flatten, or create child datasets with `CommandText: "$.ds.result.Collection.*"`
