• What is the cause and solution for SAP error message WZRE_EXT_POST022 - &1 is not a structure ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message: WZRE_EXT_POST022 &1 is not a structure
  
  Cause:
  This error occurs when the program or function module expects a structure type for a particular parameter or variable, but the actual data object passed or referenced is not a structure. Instead, it might be a table, a simple data element, or an incompatible type.
  In SAP, structures are defined data types consisting of multiple fields (like a record), whereas tables are collections of rows, and simple data elements are single fields. The error indicates a mismatch in the expected data type.
  The placeholder &1 in the message will be replaced by the name of the variable or parameter that is not a structure.
  
  Typical Scenarios:
  
  Passing an internal table where a structure is expected.
  Using a data element or domain instead of a structure.
  Incorrectly referencing a field symbol or data reference.
  Mistake in the interface of a function module, method, or BAdI implementation where the parameter type is wrongly defined or used.
  
  
  Solution:
  
  
  Check the Data Type:
  
  Identify the variable or parameter mentioned in the error message.
  Use transaction SE11 or SE80 to check the data type of this variable.
  Confirm whether it is a structure or not.
  
  
  
  Correct the Data Type:
  
  If the variable is not a structure but should be, redefine it as a structure.
  If the program expects a structure but you have an internal table, either:
  
  Pass a single row of the table (a structure), or
  Change the program logic to handle a table instead of a structure.
  
  
  
  
  
  Adjust the Code:
  
  If you are using field symbols or data references, ensure they point to a structure.
  Use DESCRIBE FIELD or TYPE statements to verify the type at runtime if needed.
  
  
  
  Check Interface Definitions:
  
  For function modules, methods, or BAdIs, verify the parameter definitions in SE37, SE24, or SE18.
  Make sure the parameter types match the expected structure types.
  
  
  
  Debugging:
  
  Set a breakpoint before the error occurs.
  Inspect the variable's type and contents.
  Trace back to where the variable is assigned or passed.

  SAP Notes: Search for specific notes related to WZRE_EXT_POST022 if this error occurs in a standard SAP add-on or module.
  
  
  Example:
  If the error message is:
  WZRE_EXT_POST022 ZMY_STRUCTURE is not a structure
  
  Check if ZMY_STRUCTURE is defined as a structure in SE11.
  If ZMY_STRUCTURE is actually a table or a simple data element, correct the code or data definition.
  For example, if you have:
  
  DATA: ZMY_STRUCTURE TYPE TABLE OF ZMY_STRUCTURE_TYPE.
  But the program expects a structure, you should pass a single row:
  DATA: ls_my_structure TYPE ZMY_STRUCTURE_TYPE.
  
  ls_my_structure = ZMY_STRUCTURE[ 1 ].
  CALL FUNCTION 'SOME_FUNCTION'
    EXPORTING
      structure_param = ls_my_structure.
