• What is the cause and solution for SAP error message RU182 - You can only process one pool per transaction ?

  The SAP error message RU182, which states "You can only process one pool per transaction," typically occurs in the context of SAP's batch input processing or when dealing with pooled tables. This error indicates that the system is trying to process multiple pooled tables in a single transaction, which is not allowed.
  Cause:
  
  Multiple Pooled Tables: The error arises when a transaction attempts to access or modify more than one pooled table at the same time. In SAP, pooled tables are designed to be processed in isolation to maintain data integrity.
  Batch Input Sessions: If you are using batch input sessions to process data, the session may inadvertently include multiple pooled tables, leading to this error.
  Custom Programs: Custom ABAP programs that manipulate pooled tables may also trigger this error if they attempt to process multiple tables in a single transaction.
  
  Solution:
  
  Separate Transactions: Ensure that each transaction only processes one pooled table. If you need to work with multiple pooled tables, split the operations into separate transactions.
  Review Batch Input Sessions: If you are using batch input, check the session to ensure it only includes one pooled table. You may need to create separate sessions for different tables.
  Modify Custom Code: If the error is coming from a custom ABAP program, review the code to ensure that it does not attempt to access multiple pooled tables in a single transaction. Refactor the code to handle each table in its own transaction.
  Error Handling: Implement error handling in your programs to catch this specific error and provide meaningful feedback to users or logs for troubleshooting.
  
  Related Information:
  
  Pooled Tables: Pooled tables are a type of database table in SAP that allows multiple logical tables to share the same physical table in the database. They are used to optimize storage and performance for certain types of data.
  Transaction Management: Understanding how transactions work in SAP is crucial. Each transaction should ideally be atomic, meaning it should complete fully or not at all, which is why processing multiple pooled tables in one transaction is restricted.
  SAP Notes: Check SAP Notes for any updates or specific guidance related to this error. SAP frequently updates its documentation and may provide additional insights or patches.
