• What is the cause and solution for SAP error message MRBW012 - Recompilation ended due to timeout ?

  The SAP error message MRBW012 indicates that a recompilation process has ended due to a timeout. This typically occurs in the context of SAP BW (Business Warehouse) when the system is trying to recompile a query or a data model, and it takes longer than the allowed time limit.
  Cause:
  
  Long-running Queries: The recompilation process may be taking too long due to complex queries or large datasets.
  System Performance: The performance of the SAP BW system may be affected by high load, insufficient resources (CPU, memory), or other background processes.
  Configuration Settings: The timeout settings for recompilation may be set too low for the complexity of the queries being processed.
  Locks or Deadlocks: Other processes may be locking the resources needed for recompilation, causing delays.
  
  Solution:
  
  Increase Timeout Settings: Check and increase the timeout settings for recompilation in the BW system configuration. This can often be done in the BW settings or through transaction codes like RSCUSTV2.
  Optimize Queries: Review and optimize the queries that are causing the timeout. This may involve simplifying the query logic, reducing the amount of data being processed, or indexing relevant fields.
  Monitor System Performance: Use transaction codes like ST03N or ST06 to monitor system performance and identify any bottlenecks. Address any performance issues by optimizing system resources or scheduling heavy processes during off-peak hours.
  Check for Locks: Use transaction codes like SM12 to check for locks that may be affecting the recompilation process. Resolve any locks that are not needed.
  Run in Background: If recompilation is taking too long, consider running it in the background to avoid timeouts during peak usage times.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSCUSTV2 (for customizing BW settings), ST03N (for workload analysis), and SM12 (for lock entries).
  SAP Notes: Check SAP Notes for any known issues or patches related to the MRBW012 error. SAP frequently updates its knowledge base with solutions for common problems.
  Performance Tuning: Consider engaging in performance tuning for your BW system, which may involve database optimization, query optimization, and hardware upgrades if necessary.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with SAP support or your internal SAP BW team for further assistance.
