SAP Error Message - Details

• Message type: E = Error

• Message class: UPC - Planning: General Error Messages

• Message number: 092

• Message text: Requested data cannot be locked. See long text

What causes this issue?

For processing data in planning area '&V1&' the requested data has to be
locked exclusively. The data currently being requested is recorded in
a very large selection table. In order to be able to lock the data
exclusively, the system has to store a compressed version of this
selection table in the lock server. However, the compressed selection
table has more than 999 rows. So that a reasonable number of users can
work in planning, the system limits the number of records possible in a
compressed selection table. This limit is currently 999.

System Response

The requested data cannot be locked.

How to fix this error?

This situation can usually only be avoided by simplifying selections.
Consult SAP Note 635244.
If such complex selection tables occur when processing mass data, you
can separate these and execute planning functions consecutively.

Procedure for System Administrators

• What is the cause and solution for SAP error message UPC092 - Requested data cannot be locked. See long text ?

  The SAP error message UPC092, which states "Requested data cannot be locked," typically occurs in the context of data processing where a specific record or set of records is being accessed for updates or modifications. This error indicates that the system is unable to lock the requested data for the operation you are trying to perform, which can lead to issues such as data inconsistency or conflicts in multi-user environments.
  Causes of UPC092 Error
  
  
  Data Locking Conflicts: Another user or process may currently have a lock on the data you are trying to access. SAP uses locking mechanisms to prevent simultaneous updates that could lead to data inconsistencies.
  
  
  Long-Running Transactions: If a transaction is taking too long to complete, it may hold locks on the data longer than expected, preventing other transactions from accessing it.
  
  
  Database Issues: There may be underlying database issues that are causing locks to not be released properly.
  
  
  Configuration Issues: Incorrect configuration settings in the SAP system or the database can lead to locking issues.
  
  
  User Authorizations: The user may not have the necessary authorizations to lock the data.
  
  
  Solutions to UPC092 Error
  
  
  Check for Active Locks: Use transaction code SM12 to check for active locks on the data you are trying to access. If you find locks that are no longer needed, you can release them (if you have the necessary authorizations).
  
  
  Wait and Retry: If the lock is held by another user or process, you may need to wait until the lock is released before trying again.
  
  
  Review Long-Running Transactions: Identify any long-running transactions that may be holding locks and address them. This may involve optimizing the transaction or ensuring that it completes in a timely manner.
  
  
  Check User Authorizations: Ensure that the user attempting to perform the operation has the necessary authorizations to lock the data.
  
  
  Database Maintenance: If the issue persists, consider performing database maintenance or consulting with your database administrator to check for any underlying issues.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
