  The SAP error message OQ036, which states "Specify either source structure/field or method or constant value," typically occurs in the context of SAP's configuration for data transfer or mapping, particularly in the context of the SAP Advanced Business Application Programming (ABAP) or when working with data transfer processes (DTP) in SAP BW (Business Warehouse).
  Cause:
  This error usually arises when a required field or parameter is not specified in a configuration or mapping process. Specifically, it indicates that the system expects either:
