• What is the cause and solution for SAP error message RD308 - Units of measure for transfer structure and value field do not concur ?

  The SAP error message RD308 indicates that there is a mismatch between the units of measure (UoM) defined for a transfer structure and the value field in a data transfer process. This typically occurs in the context of data transfer processes (DTP) in SAP BW (Business Warehouse) or when dealing with data extraction and loading.
  Cause:
