The target information structure &V1& has a different type than source
information structure &V2&.

System Response

Particularly when you copy from type 'without period' to a different
info structure type, the period information is lost.

• What is the cause and solution for SAP error message M2574 - Target info structure & does not have the same type as source structure & ?

  The SAP error message M2574 indicates a mismatch between the target and source structures in a data transfer or mapping process. This typically occurs when you are trying to transfer data between two structures (like internal tables, database tables, or data elements) that do not have compatible data types or formats.
  Cause:
  
  Data Type Mismatch: The fields in the source structure and target structure have different data types (e.g., one is a character type and the other is a numeric type).
  Field Length Differences: The lengths of the fields in the source and target structures may not match, leading to truncation or overflow issues.
  Incompatible Structures: The structures may have different field names or orders, which can cause issues during data transfer.
  Custom Fields: If you are using custom fields or structures, ensure that they are defined correctly and consistently across both structures.
  
  Solution:
  
  
  Check Data Types: Verify that the data types of corresponding fields in both the source and target structures are the same. If they are not, you may need to convert the data type in your ABAP code or adjust the structure definitions.
  
  
  Align Field Lengths: Ensure that the lengths of the fields in both structures match. If necessary, adjust the field lengths in the target structure to accommodate the source structure.
  
  
  Review Structure Definitions: If you are using custom structures, double-check their definitions in the Data Dictionary (SE11) to ensure they are consistent.
  
  
  Modify ABAP Code: If you are writing ABAP code to transfer data, ensure that you are correctly mapping the fields from the source to the target structure. You may need to use conversion functions or explicit type casting.
  
  
  Use Data Mapping Tools: If applicable, use data mapping tools or transformation functions provided by SAP to handle data type conversions automatically.
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and SE37 (Function Builder) to check and modify structures and data types.
  Debugging: If you encounter this error during runtime, consider using the debugger to step through the code and identify where the mismatch occurs.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message, as there may be specific fixes or recommendations provided by SAP.
  
  By addressing the data type and structure mismatches, you should be able to resolve the M2574 error and successfully transfer your data.
