• What is the cause and solution for SAP error message RAP_CMP_CHECKS051 - Target multiplicity changed for navigation property &1 of entity &2. ?

  The SAP error message RAP_CMP_CHECKS051 indicates that there is a problem with the target multiplicity of a navigation property in your RAP (Rapid Application Programming) model. This typically occurs when the expected cardinality of a relationship between entities has been changed or is inconsistent with the defined model.
  
  Cause:
  
  Inconsistent Cardinality: The navigation property defined in your entity might have a different cardinality than what is expected. For example, if a navigation property is defined as one-to-many (1..n) but is being treated as one-to-one (1..1) in some part of your model, this inconsistency will trigger the error.
  Model Changes: If there have been recent changes to the data model or the underlying database schema that affect the relationships between entities, this can lead to mismatches in expected multiplicity.
  Incorrect Annotations: The annotations used in your CDS (Core Data Services) views might not correctly reflect the intended relationships, leading to confusion in the model.
