• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG055 - The composition does not use consistent primary keys ?

  The SAP error message SADL_GEN_DRFT_MSG055 indicates that there is an inconsistency in the primary keys used in a composition. This typically occurs in the context of SAP's Semantic Data Model (SDM) or when working with the SAP ABAP programming model for SAP Fiori applications, particularly when defining or using data models that involve multiple entities.
  Cause
  The error arises when the primary keys defined for the entities in a composition do not match or are not consistent. This can happen due to several reasons:
  
  
  Mismatched Key Fields: The key fields defined in the different entities of the composition do not align. For example, if one entity uses a combination of fields as a primary key while another entity uses a single field, this inconsistency will trigger the error.
  
  
  Incorrect Data Model Definition: The data model may have been incorrectly defined, leading to inconsistencies in how the primary keys are set up across different entities.
