• What is the cause and solution for SAP error message AD608 - Field & must be last field and of type 'RAW' ?

  The SAP error message AD608 indicates that a specific field in a data structure or table must be the last field and must be of type 'RAW'. This error typically arises in the context of ABAP programming, particularly when dealing with data structures, internal tables, or database tables that are being defined or modified.
  Cause:
  
  Field Positioning: The error occurs when a field that is supposed to be of type 'RAW' is not positioned as the last field in the structure or table definition.
  Data Type Mismatch: The field in question is not defined as type 'RAW', which is required for the specific context in which it is being used.
  Incorrect Structure Definition: The structure or table definition does not adhere to the expected format or requirements set by SAP.
  
  Solution:
  
  Check Field Definition: Ensure that the field in question is defined as type 'RAW'. You can do this by checking the data dictionary (SE11) or the ABAP code where the structure is defined.
  Reposition the Field: If the field is not the last field in the structure, move it to the end of the field list. In ABAP, the last field in a structure can often be a 'RAW' type field used for binary data.
  Review Documentation: Consult the SAP documentation or the specific module documentation to understand the requirements for the structure or table you are working with.
  Test Changes: After making the necessary changes, activate the object and test to ensure that the error is resolved.
