• What is the cause and solution for SAP error message WER070 - Data supplied for structure &1 is not compatible with a table type ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WER070 - Data supplied for structure &1 is not compatible with a table type
  
  Cause:
  This error occurs when a data object (usually a structure) is passed or assigned to a parameter or variable that expects a table type (internal table), or vice versa. In other words, the data type of the actual parameter does not match the expected data type of the formal parameter in a function module, method, or subroutine call.
  For example, if a function module expects an internal table as input, but a structure (single record) is passed instead, this error will be raised.
  
  Typical Scenarios:
  
  Passing a structure where an internal table is expected.
  Assigning a structure to a variable declared as a table type.
  Mismatch in data types during parameter passing in function modules, methods, or subroutines.
  Incorrect use of TABLES or USING parameters in function modules or methods.
  
  
  Solution:
  
  
  Check the Data Types:
  
  Verify the data type of the parameter in the called function module, method, or subroutine.
  Check the data type of the actual parameter you are passing.
  
  
  
  Correct the Parameter Passing:
  
  If the called routine expects an internal table, pass an internal table.
  If you have a structure but need to pass a table, you can create an internal table with one row containing the structure.
  
  Example:
  DATA: ls_data TYPE your_structure,
        lt_data TYPE TABLE OF your_structure.
  
  " If function expects a table, fill the table with the structure
  APPEND ls_data TO lt_data.
  CALL FUNCTION 'YOUR_FUNCTION'
    TABLES
      your_table_param = lt_data.
  
  
  Adjust the Declaration:
  
  If you mistakenly declared a parameter as a structure instead of a table, correct the declaration.
  
  
  
  Use Correct Parameter Keywords:
  
  Use TABLES for internal tables.
  Use USING or CHANGING for structures or single records.
  
  
  
  Check the Interface:
  
  Use transaction SE37 (Function Builder) or SE24 (Class Builder) to check the interface of the called routine.
  
  
  
  
  Related Information:
  
  ABAP Data Types: Understanding the difference between structures and internal tables is crucial.
  Function Module Parameter Passing: Parameters can be passed by value, reference, or as tables.
  Debugging: Use the debugger to check the actual data types at runtime.
  SAP Notes: Sometimes, specific SAP Notes may address issues related to this error in standard SAP function modules.
  
  
  Summary:
  
  Error: Passing a structure where a table is expected (or vice versa).
  Fix: Match the data types correctly; convert structure to table if needed.
  Check: Parameter definitions in the called routine.
