Symptom

  • ABSL syntax highlighting/color coding is not working in .absl files; all code appears as plain text.
  • Breakpoints cannot be placed in .absl files.
  • Error message displayed on every attempted breakpoint: "This is not a valid location for a breakpoint".
  • Both issues started immediately after a system upgrade.

Environment

Reproducing the Issue

  1. Open Visual Studio with SAP Cloud Applications Studio VSIX 2605 installed.
  2. Open any .absl file from Solution Explorer.
  3. Observe that all code appears in plain text with no color differentiation.
  4. Click on any line to place a breakpoint.
  5. Observe the error message: "This is not a valid location for a breakpoint".
  6. Try to extend a Standard Business Object such as Supplier or Employee 

Cause

You are using Visual Studio Enterprise 2026 (version 18.5.2), which is not supported by SAP for SAP Cloud Applications Studio.

Resolution

  1. Install and use a supported Visual Studio version (Visual Studio 2022).
  2. Install the latest compatible SAP Cloud Applications Studio VSIX extension for the supported Visual Studio version.
  3. Reopen the solution and open a .absl file to confirm syntax highlighting is restored.
  4. Set a breakpoint on a valid code line to verify that breakpoints are accepted and functional.
