  The SAP error message APS_CKE_PARSER103, which states "Changing the primary data source is incompatible," typically occurs in the context of SAP Analytics Cloud (SAC) or SAP BusinessObjects when there is an issue with the data source configuration in a model or story. This error indicates that the system is unable to change the primary data source due to compatibility issues with the existing data model or story.
  Causes:
  
  Incompatible Data Sources: The new primary data source may not be compatible with the existing data model. This can happen if the structure, data types, or relationships of the new data source differ significantly from the original.
  Data Model Dependencies: The existing model may have dependencies on the original primary data source, such as calculated measures, dimensions, or hierarchies that are not present in the new data source.
  Data Source Type: The type of data source (e.g., live connection vs. import) may differ, leading to incompatibility.
  Data Source Configuration: The configuration settings of the new data source may not match the requirements of the model or story.
  
  Solutions:
  
  Check Compatibility: Ensure that the new primary data source has a compatible structure with the existing data model. This includes checking the fields, data types, and relationships.
  Update Model/Story: If the new data source is necessary, consider updating the model or story to accommodate the new data source. This may involve redefining measures, dimensions, and hierarchies.
  Create a New Model: If the changes are extensive, it may be more efficient to create a new model using the new primary data source rather than trying to modify the existing one.
  Review Dependencies: Analyze any dependencies in the model that may be causing the incompatibility. Remove or adjust these dependencies as needed.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to your version of SAP and the data sources you are using.
