• What is the cause and solution for SAP error message MC360 - Function module & already exists and was not deleted ?

  The SAP error message MC360 typically indicates that there is an issue with a function module that is trying to create or modify a record that already exists in the system. This error is often encountered in the context of Material Management (MM) or Production Planning (PP) modules, particularly when dealing with master data or transactional data.
  Cause:
  The error message "Function module & already exists and was not deleted" usually arises due to one of the following reasons:
  
  
  Duplicate Entries: The system is attempting to create a record that already exists in the database. This can happen if there is an attempt to create a new material, vendor, or other master data that has the same key as an existing record.
  
  
  Data Inconsistency: There may be inconsistencies in the data being processed, such as incorrect or incomplete data being sent to the function module.
  
  
  Transaction Errors: The error can also occur if there are issues with the transaction being executed, such as missing parameters or incorrect configurations.
  
  
  Custom Code: If there are custom developments or enhancements in the system, they may inadvertently lead to this error if they do not handle existing records properly.
  
  
  Solution:
  To resolve the MC360 error, you can take the following steps:
  
  
  Check for Existing Records: Verify if the record you are trying to create already exists in the system. Use transaction codes like SE16 or SE11 to check the relevant database tables.
  
  
  Review Input Data: Ensure that the data being passed to the function module is correct and does not contain duplicates. Validate the input parameters and ensure they are complete.
  
  
  Delete or Modify Existing Records: If the record already exists and is not needed, consider deleting it or modifying it as necessary. Ensure that you have the appropriate authorizations to perform these actions.
  
  
  Debugging: If you have access to the ABAP development environment, you can debug the function module to identify where the error is occurring. This can help you understand why the system is trying to create a duplicate entry.
  
  
  Consult Documentation: Review the SAP documentation or notes related to the specific function module you are using. There may be specific guidelines or known issues that can help you resolve the error.
  
  
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. Provide them with detailed information about the error, including the transaction code, function module name, and any relevant logs.
