  The SAP error message APS_CKE_PARSER102, which states "Changing the parameter mapping of primary data source is incompatible," typically occurs in the context of SAP Analytics Cloud (SAC) or SAP BusinessObjects when there are issues related to the data source configuration, particularly when modifying the parameter mapping of a primary data source that is already in use.
  Cause:
  
  
  Incompatible Changes: The error is triggered when you attempt to change the parameter mapping of a primary data source that is already being used in a model, story, or report. This can happen if:
  
  You modify the data source's parameters in a way that conflicts with existing mappings.
  The data source is linked to other objects that depend on its current configuration.
  
  
  
  Data Source Dependencies: If the primary data source is linked to other models, stories, or reports, changing its parameters can lead to inconsistencies or conflicts.
  
  
  Versioning Issues: If there are multiple versions of the data source or if the data source has been updated in a way that is not compatible with existing references.
  
  
  Solution:
  
  
  Revert Changes: If possible, revert the changes made to the parameter mapping of the primary data source to its previous state. This should resolve the incompatibility.
  
  
  Check Dependencies: Review all models, stories, and reports that are using the primary data source. Ensure that any changes you want to make do not conflict with existing configurations.
  
  
  Create a New Data Source: If you need to change the parameter mapping significantly, consider creating a new data source with the desired parameters instead of modifying the existing one. This way, you can avoid conflicts with existing objects.
  
  
  Update References: If you must change the parameter mapping, ensure that all dependent objects (models, stories, etc.) are updated to reflect the new mapping.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to your version of SAP Analytics Cloud or BusinessObjects, as there may be version-specific considerations.
