ABAP SmartFix

Auto Fix ATC Findings, Pragmas and Modern Syntax for SAP ABAP

A VS Code extension for SAP ABAP development. It lists the ATC / Code Inspector findings in your ABAP code and fixes them automatically:

• Safe rewrites are applied to the code directly, e.g. SELECT SINGLE → SELECT … UP TO 1 ROWS … ENDSELECT, MOVE a TO b → b = a, commenting out BREAK-POINT.
• Everything else gets a Pragma (##…) or Pseudo Comment ("#EC …), placed at the right position even in multi-line and chained statements.
• Anything that can be done neither way is marked for manual fixing, and a complete prompt can be generated for your AI assistant.

Requirements

VS Code 1.75 or later. No Node.js and no SAP connection needed.

Usage

1. Open an .abap file and run ABAP SmartFix: Analyze Current File (from the editor context menu, the editor title button, or automatically on save).

2. Findings are shown in:

   • Problems panel: one diagnostic per finding; auto-fixable ones are marked [Auto-fixable].
   • ABAP SmartFix sidebar: findings grouped by file with their fix; click one to jump to the line.
   • Status bar: the total number of findings.

   While you type, an analyzed file is analyzed again once typing pauses (about 0.5 s), so line numbers stay current. Closing a file removes its findings; files that were only scanned by Analyze Workspace and never opened stay listed.

3. Right-click in the editor and pick how to fix them:

To fix a whole project, use Analyze Workspace and then Auto Fix All Scanned Files in the sidebar. All changes are applied as one edit, so a single Ctrl+Z undoes them; files are not saved automatically.

More commands: Generate Markdown Report, Export JSON, Show Rules, Clear Results.

After an auto fix, run the syntax check and ATC again in your SAP system.

Auto fix on save

"[abap]": {
  "editor.codeActionsOnSave": { "source.fixAll.abap-smartfix": "explicit" }
}

Supported checks

Run Show Rules for each rule's id and exact trigger conditions.

Settings

Example:

{
  "abap-smartfix.suppressStyle": "pragma",
  "abap-smartfix.ruleFixModes": { "select-single": "suppress" },
  "abap-smartfix.disabledRules": ["select-no-order-by"]
}

Custom rules

Put a .abap-smartfix-rules.json in the workspace root to add annotation or rewrite rules:

[
  {
    "id": "commit-work",
    "token": "\"#EC CI_COMMIT",
    "title": "COMMIT WORK",
    "match": "^COMMIT\\s+WORK\\b"
  },
  {
    "id": "translate-upper",
    "title": "TRANSLATE … TO UPPER CASE → to_upper( )",
    "match": "^TRANSLATE\\s+(\\S+)\\s+TO\\s+UPPER\\s+CASE$",
    "replace": "$1 = to_upper( $1 )"
  }
]

match is tested against a single statement (multi-line statements are joined and comments removed). A token starting with ## is a Pragma; anything else is a Pseudo Comment. replace can use $1, $2. Other fields: notMatch, flags, why, severity, safety (safe / review), enabled.

Known issues

• This is a lightweight syntax scanner, not a full ABAP parser. It cannot see macro expansion, INCLUDE chains, cross-program calls or DDIC information.
• Accepted annotation names can differ between SAP releases and custom ATC checks. Go by the messages in your system and adjust with abap-smartfix.tokenOverrides if needed.
• ##NEEDED only looks at the current file. Global declarations in TOP includes are skipped to avoid flagging variables used in other includes or dynpros.
• Annotations only make ATC skip a check; they do not improve the code. Real problems (such as a SELECT inside a loop) are better fixed in code.

If you find a false positive or a missed finding, please report it with a minimal code sample.
