How To Fix UGWB150 - Maintenance is done in another transaction

SAP Error Message - Details

• Message type: E = Error

• Message class: UGWB - Messages for Workbench

• Message number: 150

• Message text: Maintenance is done in another transaction

What causes this issue?

To execute the function you have chosen, the system needs to launch a
transaction within the transaction that is currently running.

System Response

Changes you have made in the current transaction, but have not yet saved
, are ignored in the context of the other transaction. This has the
following consequences:
Saving changes you make in the other transaction only saves the changes
of the other transaction. This does not save the changes you have made
up to now in the consolidation workbench.
The unsaved changes in the consolidation workbench are also lost if you
exit the other transaction in a way that does not take you back to the
present workbench transaction (for example, by logging off the system or
by starting yet another transaction).

How to fix this error?

Proceed with caution when navigating in the other transaction. Before
launching another transaction from within the consolidation workbench,
as a precaution you should save the changes you have made in the
consolidation workbench.

Procedure for System Administrators

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 UGWB150 - Maintenance is done in another transaction ?

  The SAP error message UGWB150, which states "Maintenance is done in another transaction," typically occurs when a user attempts to make changes to a record that is currently being edited or locked by another user or transaction. This is a common issue in SAP systems where multiple users may be accessing the same data simultaneously.
  Cause:
  
  Record Locking: The most common cause of this error is that the record you are trying to edit is locked by another user or transaction. SAP uses a locking mechanism to prevent data inconsistencies when multiple users attempt to modify the same data at the same time.
  Long-running Transactions: If a transaction takes a long time to complete, it may hold the lock on the record for an extended period, leading to this error for other users.
  Background Jobs: Sometimes, background jobs or processes may also lock records, causing this error for users trying to access the same data.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for a few moments and then try to access the record again. If the other user or transaction completes its work, the lock will be released.
  Identify the Lock: You can use transaction code SM12 to check for locks on the record. This transaction allows you to see which user or process is holding the lock. If you have the necessary authorizations, you can also release the lock.
  Communicate with Users: If you identify that a specific user is holding the lock, you may want to communicate with them to understand if they can complete their transaction or release the lock.
  Check for Background Jobs: If a background job is causing the lock, you may need to wait for it to complete or check with your system administrator to see if it can be stopped or rescheduled.
  Review Transaction Logic: If this error occurs frequently, it may be worth reviewing the transaction logic or process to minimize locking issues, such as optimizing long-running transactions or implementing better user training.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks), SM21 (to check system logs), and ST22 (to check dumps) for troubleshooting.
  User Authorizations: Ensure that users have the appropriate authorizations to view and manage locks if necessary.
