• What is the cause and solution for SAP error message SWF_FLEX_CDS001 - Generated class '&1' has been manually changed. ?

  The SAP error message SWF_FLEX_CDS001 indicates that a generated class in the context of SAP Workflow or a related component has been manually changed. This typically occurs when the system detects that the source code of a generated class has been modified outside of the standard generation process, which can lead to inconsistencies and issues in the application.
  Cause:
  
  Manual Changes: The most common cause is that someone has manually edited the generated class, which is not recommended as these classes are meant to be generated automatically by the system.
  Transport Issues: If the class was transported from another system and the transport did not include the latest version of the generated class, it may lead to discrepancies.
  Development Environment: Changes made in a development environment that were not properly managed or transported to the production environment can also trigger this error.
  
  Solution:
  
  Revert Changes: If possible, revert the changes made to the generated class. You can do this by restoring the class to its original state from the version control or by regenerating it.
  Regenerate the Class: Use the appropriate transaction (like SE80 or SE11) to regenerate the class. This will overwrite any manual changes and restore the class to its generated state.
  Check for Dependencies: Ensure that any dependencies or related objects that might have been affected by the manual changes are also checked and corrected.
  Review Transport Requests: If the issue arose after a transport, review the transport requests to ensure that all necessary objects were included and correctly transported.
  Consult Documentation: Refer to SAP documentation or notes related to the specific component you are working with for any additional guidance or known issues.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific notes related to the error message SWF_FLEX_CDS001. SAP frequently updates their knowledge base with solutions for common issues.
  Version Control: If your organization uses version control for ABAP code, check the history of the class to identify what changes were made and by whom.
