• What is the cause and solution for SAP error message M2348 - Data target and source must be identical ?

  The SAP error message M2348, which states "Data target and source must be identical," typically occurs in the context of data transfer processes, particularly when working with SAP's Material Management (MM) or other modules that involve data movement between different systems or tables.
  Cause:
  This error usually arises when there is a mismatch between the source and target data structures during a data transfer operation. Common causes include:
  
  
  Different Data Structures: The source and target data structures (e.g., fields, data types) do not match. This can happen if the source data is coming from a different table or structure that does not align with the target.
  
  
  Inconsistent Data Types: The data types of the fields in the source and target do not match. For example, if the source field is a character type and the target field is a numeric type, this can lead to the error.
  
  
  Missing Fields: If the target structure expects certain fields that are not present in the source structure, this can trigger the error.
  
  
  Configuration Issues: Incorrect configuration in the data transfer process, such as incorrect mapping or transformation rules, can also lead to this error.
  
  
  Solution:
  To resolve the M2348 error, you can take the following steps:
  
  
  Check Data Structures: Verify that the source and target data structures are identical. This includes checking field names, data types, and lengths.
  
  
  Field Mapping: Ensure that the field mapping between the source and target is correctly defined. If you are using a data transfer tool or process, review the mapping configuration.
  
  
  Data Type Compatibility: Make sure that the data types of corresponding fields in the source and target are compatible. If necessary, adjust the data types in the source or target to ensure they match.
  
  
  Review Configuration: If you are using a specific data transfer process (like a data transfer routine or a batch job), review the configuration settings to ensure they are set up correctly.
  
  
  Test with Sample Data: If possible, test the data transfer with a small set of sample data to identify where the mismatch occurs.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to the data transfer process you are using.
  
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may be using transaction codes like MM01, MM02, or others related to material management or data transfer.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Data Transfer Tools: Familiarize yourself with the data transfer tools or methods you are using, such as LSMW (Legacy System Migration Workbench), BAPIs, or IDocs, as they may have specific requirements for data structure alignment.
  
  By following these steps, you should be able to identify and resolve the cause of the M2348 error in your SAP environment.
