CJ626 - Details

• The SAP error message CJ626 ("You can only change from numeric to alphanumeric sections") typically occurs in the context of project management within SAP, particularly when dealing with Work Breakdown Structures (WBS) or project definitions. This error indicates that there is an attempt to change the structure of a project or WBS element from a numeric format to an alphanumeric format, which is not allowed in SAP.
  
  Cause:
  
  WBS Element Format: The WBS element is defined as numeric (e.g., 1, 1.1, 1.1.1) and you are trying to change it to an alphanumeric format (e.g., A1, A1.1).
  Project Structure: The project structure may have been initially set up with numeric identifiers, and SAP does not allow changing the format once it has been established.
  Data Integrity: SAP enforces this rule to maintain data integrity and consistency within the project management module.
  
  
  Solution:
  
  Check the Format: Review the WBS element or project definition you are trying to change.
