• What is the cause and solution for SAP error message D0104 - Field & of type & must be in the final position ?

  The SAP error message D0104 ("Field & of type & must be in the final position") typically occurs during the development of ABAP programs or when working with data structures, particularly when defining the layout of internal tables or structures. This error indicates that a field of a certain type is not positioned correctly according to the rules of the data structure definition.

  Consult Documentation: Refer to the SAP documentation or ABAP programming guidelines for specific rules regarding field positioning and data types.
