• What is the cause and solution for SAP error message NJIT_O_MSG050 - plant and material combination exists for the new record ?

  The SAP error message NJIT_O_MSG050 indicates that there is an attempt to create a new record for a combination of plant and material that already exists in the system. This typically occurs in scenarios where you are trying to create a new entry in a table or a master data record (such as material master, purchasing info records, etc.) that requires a unique combination of plant and material.
  Cause:
  
  Duplicate Entry: The most common cause is that the combination of the plant and material you are trying to enter already exists in the database.
  Data Migration: If you are migrating data from another system or performing mass uploads, there may be duplicates in the data being uploaded.
  Incorrect Input: The user may have mistakenly entered the same plant and material combination.
  
  Solution:
  
  
  Check Existing Records: Before creating a new record, check the existing records in the relevant table to see if the combination of plant and material already exists. You can do this by using transaction codes like SE16 or SE11 to view the relevant database table.
  
  
  Modify Existing Record: If the combination already exists and you need to update it, consider modifying the existing record instead of creating a new one.
  
  
  Data Validation: Implement data validation checks in your data entry process to prevent duplicate entries. This can be done through user exits or BAdIs.
  
  
  Data Cleanup: If you are migrating data, ensure that your data is clean and does not contain duplicates before performing the upload.
  
  
  Consult Documentation: Review the relevant SAP documentation or consult with your SAP support team for specific guidance related to the module you are working with.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material) to manage material master data.
