SAP Error Message - Details

• Message type: E = Error

• Message class: FINB_CONFIG - Financials Configuration

• Message number: 100

What causes this issue?

Configuration settings are buffered in the shared buffer of the
application server. After changes have been made to the configuration or
the buffer has been reset, a buffer rebuild is performed. During the
buffer rebuild, the vuffer is locked against parallel access. This
usually takes a matter of seconds.

System Response

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

How to fix this error?

Use transaction SM50 to check whether a process initiated by user &V1&
has failed to reach completion. After a session has terminated, it is
possible for the lock to continue to apply to table &V2&. You can use
transaction SM12 to delete this lock.

• What is the cause and solution for SAP error message FINB_CONFIG100 - User &1 is locking shared buffer &2 ?

  The SAP error message FINB_CONFIG100 indicates that a user is locking a shared buffer, which can prevent other users from accessing the same resource. This typically occurs in the context of financial applications within SAP, where shared buffers are used to manage data consistency and performance.
  Cause:
  
  User Locking: The user identified in the error message has an active session that is locking a shared buffer. This can happen if the user is performing a transaction that requires exclusive access to certain data.
  Long-Running Transactions: If a transaction takes a long time to complete, it can hold locks longer than necessary, causing other users to be blocked.
  Configuration Issues: There may be issues with the configuration of the shared buffer or the way transactions are being handled in the system.
  
  Solution:
  
  Identify the User: Check which user is causing the lock. You can use transaction codes like SM12 (to view and manage locks) to identify the user and the specific lock.
  Terminate the Session: If the user is not actively working on the transaction, you may need to terminate their session to release the lock. This can be done through transaction SM04 (to view active users) or SM12 (to delete locks).
  Review Transaction Logic: If the locking is due to long-running transactions, review the logic of the transaction to optimize performance and reduce the time locks are held.
  Increase Buffer Size: If the issue is related to buffer size, consider increasing the size of the shared buffer in the system configuration.
  User Training: Ensure that users are trained on how to properly complete transactions to minimize the time locks are held.
