• Message number: 188

• Message text: Data locked by user &. Display only

What causes this issue?

You are attempting to access the data of the status-indpendent
valuation methods in simplified Customzing in the change mode. However,
this data is already being processed by user &V1& in the display mode.
Because changes to the valuation methods in simplified Customizing
require changes to table TKKAS in the Expert Mode, the system must lock
this table. However, the table could not be locked because the data was
already being processed by user &V1& in the display mode.

System Response

To prevent inconsistencies, the system remains in the display mode.
Otherwise it would not be possible to assure consistency between the
data of the valuation methods in simplified Customizing and the data of
the valuation methods in the Expert Mode.

How to fix this error?

To access the data in the display mode, confirm the message.
To access the data in the change mode, exit the transaction and try
again at a later time.

• What is the cause and solution for SAP error message KQ188 - Data locked by user &. Display only ?

  The SAP error message KQ188, which states "Data locked by user &," typically occurs when a user tries to access or modify data that is currently locked by another user. This locking mechanism is a part of SAP's data integrity and concurrency control, ensuring that multiple users do not make conflicting changes to the same data simultaneously.
  Cause:
  
  User Locking: Another user is currently editing or has locked the data you are trying to access.
  Transaction Lock: The transaction you are trying to execute may have a lock on the data due to a previous operation that has not been completed or released.
  System Lock: Sometimes, system processes or background jobs may lock data for processing.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for the other user to finish their transaction may resolve the issue. You can try again after some time.
  Identify the Locking User: Use transaction code SM12 to check for locked entries. You can see which user is holding the lock and the object that is locked.
  Contact the Locking User: If you identify the user who has locked the data, you can reach out to them to see if they can release the lock.
  Release the Lock: If necessary and if you have the appropriate permissions, you can manually delete the lock entry in SM12. However, this should be done with caution, as it may lead to data inconsistencies.
  Check for Background Jobs: If a background job is causing the lock, you may need to wait for it to complete or check its status in transaction SM37.
