• What is the cause and solution for SAP error message ICA02147 - Unit CDS view must contain leading unit and its superordinate field. ?

  The SAP error message ICA02147 indicates that there is an issue with a Core Data Services (CDS) view in your SAP system. Specifically, the error states that the CDS view must contain a leading unit and its superordinate field. This typically occurs when the CDS view is expected to include a unit of measure (UoM) that is not properly defined or included in the view.
  Cause:
  
  Missing Leading Unit: The CDS view is expected to have a leading unit of measure that is not present. A leading unit is typically the primary unit of measure for a quantity field.
  Incorrect Field Definition: The fields defined in the CDS view may not be correctly set up to include the necessary unit of measure.
  Hierarchy Issues: If the CDS view is supposed to represent a hierarchy of fields, the leading unit may not be correctly associated with its superordinate field.
  
  Solution:
  
  Check the CDS View Definition: Review the definition of the CDS view in the ABAP Development Tools (ADT) or the relevant transaction (e.g., SE11 or SE80). Ensure that the leading unit of measure is included in the view.
  Add Leading Unit: If the leading unit is missing, you need to add it to the CDS view. This can be done by including the appropriate field that represents the unit of measure.
  Verify Field Associations: Ensure that the leading unit is correctly associated with its superordinate field. This may involve checking the relationships between fields in the CDS view.
  Activate the CDS View: After making changes, activate the CDS view to ensure that the changes take effect.
  Test the CDS View: Execute the CDS view to verify that the error has been resolved and that the view returns the expected results.
