• What is the cause and solution for SAP error message RSODP_ABAP_CDS118 - Association &1 ignored: Field &2 is used as unit of measure ?

  The SAP error message RSODP_ABAP_CDS118 indicates that there is an issue with an association in a Core Data Services (CDS) view where a field is being used as a unit of measure (UoM). This typically occurs when the CDS view is trying to define an association that includes a field that is not compatible with the expected data types or semantics for a unit of measure.
  Cause
  The error is caused by the following scenarios:
  
  Field Type Mismatch: The field being used in the association is defined as a unit of measure, but it is not being treated correctly in the context of the association.
  Incorrect Association Definition: The association may be incorrectly defined, leading to the system ignoring the association due to the presence of a unit of measure field.
  Semantic Issues: The field may have semantic implications that prevent it from being used in the way intended in the association.
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Review the CDS View Definition:
  
  Check the definition of the CDS view and ensure that the field being used in the association is not defined as a unit of measure or is being used correctly.
  If the field is indeed a unit of measure, consider whether it should be included in the association or if it can be handled differently.
  
  
  
  Modify the Association:
  
  If the association is not necessary, consider removing it or modifying it to exclude the unit of measure field.
  If the association is required, ensure that the fields used in the association are compatible and do not include unit of measure fields.
  
  
  
  Check Data Types:
  
  Ensure that the data types of the fields involved in the association are compatible. For example, if one field is a unit of measure, the other fields in the association should not conflict with this.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for specific guidance on handling unit of measure fields in CDS views and associations.
  
  
  
  Testing:
  
  After making changes, test the CDS view to ensure that the error is resolved and that the view behaves as expected.
