  The SAP error message /PM0/ABJ_MSG148 Application ID &1 in table &2 not unique typically indicates that there is a problem with data integrity in the specified table. This error occurs when the system expects a unique entry for a given Application ID in the specified table, but it finds multiple entries instead. 
  Cause:
  
  Data Duplication: The most common cause of this error is that there are duplicate entries for the Application ID in the specified table. This can happen due to incorrect data entry, data migration issues, or bugs in custom programs that manipulate the data.
  Configuration Issues: Sometimes, configuration settings may lead to unexpected behavior, causing duplicates to be created.
  Concurrency Issues: If multiple users or processes are trying to insert or update records simultaneously, it may lead to duplicates.
  
  Solution:
  
  
  Identify Duplicates: Use SQL queries or transaction codes (like SE16 or SE11) to check the specified table for duplicate entries of the Application ID. You can run a query like:
  SELECT Application_ID, COUNT(*)
  FROM <table_name>
  GROUP BY Application_ID
  HAVING COUNT(*) > 1;
  Replace <table_name> with the actual name of the table mentioned in the error message.
  
  
  Remove Duplicates: Once you identify the duplicates, you will need to decide how to handle them. This could involve:
  
  Deleting the duplicate entries if they are not needed.
  Merging the data if the duplicates contain different information that needs to be preserved.
  
  
  
  Check Data Entry Processes: Review the processes that lead to data entry in the table to ensure that they are not allowing duplicates. This may involve:
  
  Implementing checks in user interfaces.
  Adding constraints in the database to prevent duplicates.
  
  
  
  Review Custom Code: If there are custom programs or enhancements that interact with the table, review the code to ensure it is not inadvertently creating duplicates.
  
  
  Consult Documentation: Check SAP notes or documentation related to the specific application or module you are working with for any known issues or additional guidance.
