• What is the cause and solution for SAP error message DO850 - No row type or data type was specified ?

  The SAP error message DO850 ("No row type or data type was specified") typically occurs in the context of ABAP programming, particularly when dealing with internal tables or data structures. This error indicates that the system is unable to determine the type of data that is being processed, which can happen for several reasons.
  Causes:
  
  Undefined Data Type: The internal table or data structure has not been defined properly, or the data type is not specified.
  Incorrect Declaration: The declaration of the internal table or structure might be incorrect or incomplete.
  Dynamic Programming Issues: If you are using dynamic programming techniques (like dynamic internal tables), the type might not be specified correctly.

  Use Strong Typing: Avoid using generic types unless necessary. Always try to use specific types to prevent ambiguity.
  Debugging: Use the debugger to trace where the error occurs. Check the context in which the internal table or structure is being used.
  Review Dynamic Operations: If you are performing operations dynamically (like using ASSIGN), ensure that the target variable has a defined type.
