Here’s a breakdown of the cause, potential solutions, and related information:

  Not exceed the maximum length (usually 30 characters).
  
  
  
  Modify the Data Source Name: If the name contains invalid characters or is empty, modify it to comply with the naming rules. For example, replace special characters with underscores or remove them entirely.
  
  
  Review Configuration: If you are creating or configuring a data source, double-check the settings in the relevant transaction (e.g., /SAPAPO/TSM for data source management) to ensure that all fields are filled out correctly.
  
  
  Check for Existing Data Sources: If you are trying to create a new data source with a name that already exists, consider using a different name.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on naming conventions for data sources in your version of SAP APO.
