How To Fix STGR049 - A line with entries &1 &2 &3 already exists, no duplicate keys allowed

SAP Error Message - Details

• Message type: E = Error

• Message class: STGR - Hold store grouping messages

• Message number: 049

• Message text: A line with entries &1 &2 &3 already exists, no duplicate keys allowed

What causes this issue?

The grid already contains the combination that you chose. Lines cannot
be duplicated.
Even if the existing line where that combination is found is marked as
deleted, the system considers that line to be an existing line.

How to fix this error?

Choose another vendor, vendor sub-range, and/or plant to create a
distinct line.
You cannot simply delete the line from the grid before creating a
similar one since the deletion is conditional to the modifications
being saved. If you did not save before attemping to create a similar
line, the line to be deleted still exists in the grid; you must save
first and then create a new line.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message STGR049 - A line with entries &1 &2 &3 already exists, no duplicate keys allowed ?

  The SAP error message STGR049 indicates that there is an attempt to create or modify a line in a table or data structure where a duplicate key already exists. This typically occurs in scenarios where unique constraints are enforced, and the system is trying to insert or update a record that would violate these constraints.
  Cause:
  
  Duplicate Entries: The most common cause is that the data you are trying to enter already exists in the system. This could be due to a previous entry that was not properly deleted or updated.
  Incorrect Data Handling: If the data is being imported or processed in bulk, there may be issues in the data handling logic that lead to duplicates being generated.
  Configuration Issues: Sometimes, configuration settings in the system may lead to unexpected behavior, causing duplicates to be created.
  
  Solution:
  
  Check Existing Entries: Before attempting to create or modify the entry, check the existing records in the relevant table or data structure to ensure that the key combination you are trying to use does not already exist.
  Modify the Data: If duplicates are found, you may need to modify the data you are trying to enter to ensure it is unique. This could involve changing key fields or removing existing entries if they are no longer needed.
  Data Cleanup: If duplicates are present in the system, you may need to perform a cleanup operation to remove or consolidate these entries.
  Review Data Import Logic: If the error occurs during a data import process, review the logic to ensure that it correctly handles existing records and does not attempt to insert duplicates.
  Consult Documentation: Check SAP documentation or support resources for specific guidance related to the transaction or module you are working with, as there may be additional considerations or best practices.
