How To Fix RSPLS092 - Requested data cannot be locked (-> see long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: RSPLS - General Messages

• Message number: 092

• Message text: Requested data cannot be locked (-> see long text)

What causes this issue?

In order to edit data from InfoProvider '&V1&', the requested data has
to be locked exclusively for user '&V2&'. The data that is currently
being requested is specified by a very large selection table. In order
to lock the data exclusively, the system has to store a compressed
version of this selection table on the SAP standard lock server.
However, the compressed selection table still has more than 999 rows. So
that a reasonable number of users are able to change data at the same
time, the system limits the number of records allowed in a selection
table to 999 records.
Information on Context of Lock Request:
Lock requests can come from BW Planning or from BW-BPS. The context
specifies the following information:
BW Planning: <ZH>{InfoProvider}{Query}</> for a lock request from a
query, <ZH>{InfoProvider}{Planning Function}{Filter}</> for a lock
request from a planning function.
BW-BPS: <ZH>{Planning Area}{Planning Level}{Planning Package}{Planning
Function}{Parameter Group}</>. For lock requests from manual planning
the following is true: Planning function = '0-MP' and the parameter
group is the technical name of the planning layout.
InfoProvider '&V1&' is always a Basis InfoProvider. The current context
information is:
'&V3&&V4&'

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 RSPLS092 - Requested data cannot be locked (-> see long text) ?

  The SAP error message RSPLS092, which states "Requested data cannot be locked," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with data locking during a query execution or data processing task. This error can arise due to various reasons, including concurrent access to the same data by multiple users or processes, or issues with the underlying database.
  Causes:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same data simultaneously, leading to a locking conflict.
  Long-Running Transactions: A transaction that takes too long to complete may hold locks on the data, preventing other transactions from accessing it.
  Database Locking Mechanism: The database may have its own locking mechanisms that prevent access to certain data when it is being modified.
  System Performance Issues: High system load or performance issues can lead to delays in releasing locks.
  Configuration Issues: Incorrect configuration settings in SAP BW or the underlying database can lead to locking problems.
  
  Solutions:
  
  Check for Active Sessions: Use transaction codes like SM12 (to check for locks) and SM21 (to check system logs) to identify any active sessions that may be holding locks on the data.
  Terminate Long-Running Transactions: If you identify any long-running transactions that are holding locks, consider terminating them if appropriate.
  Retry the Operation: Sometimes, simply retrying the operation after a short wait can resolve the issue, especially if it was caused by a temporary locking conflict.
  Optimize Queries: Review and optimize the queries or processes that are causing the locking issues to reduce the likelihood of conflicts.
  Database Maintenance: Ensure that regular database maintenance is performed to optimize performance and reduce locking 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.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks), SM21 (to view system logs), and ST22 (to check for dumps).
  SAP BW Documentation: Review SAP BW documentation for best practices on data loading and query execution to minimize locking issues.
  Performance Monitoring: Use tools like ST03N to monitor system performance and identify any bottlenecks that may be contributing to locking issues.
  
  If the problem persists after trying the above solutions, it may be necessary to involve your SAP Basis team or SAP support for further investigation.
