• What is the cause and solution for SAP error message DO846 - No row type or data type was specified ?

  The SAP error message DO846 ("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 referenced, 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 missing or incorrect.
  Dynamic Programming Issues: If you are using dynamic programming techniques (like dynamic internal tables), the type might not be defined at runtime.
  Missing Type Reference: When using generic types or references, the specific type may not have been provided.
  
  Solutions:
  
  
  Check Declarations: Ensure that all internal tables and structures are declared with a specific type. For example:
  TYPES: BEGIN OF ty_example,
           field1 TYPE c LENGTH 10,
           field2 TYPE i,
         END OF ty_example.
  
  DATA: it_example TYPE TABLE OF ty_example.
  
  
  Use Explicit Types: When declaring internal tables, always specify the row type explicitly. For example:
  DATA: it_table TYPE TABLE OF ty_example.
  
  
  Dynamic Types: If you are using dynamic types, ensure that you are correctly defining the type at runtime. You can use CREATE DATA to create a data reference dynamically.
  DATA: lr_table TYPE REF TO data.
  CREATE DATA lr_table TYPE TABLE OF ty_example.
  
  
  Check for Typos: Ensure there are no typographical errors in your type declarations or references.
  
  
  Debugging: Use the debugger to trace where the error occurs and check the types of the variables involved.
