GR374 - Details

• The SAP error message GR374 typically indicates that a library is being used by a parallel report, which can lead to issues when trying to execute certain operations that require exclusive access to that library. This error often arises in the context of background processing or when multiple users or processes are trying to access the same resource simultaneously.
  
  Cause:
  
  Parallel Processing: The error occurs when a library (such as a function module or a program) is being accessed by multiple parallel processes. SAP restricts certain operations to ensure data integrity and consistency.
  Locking Mechanism: SAP uses a locking mechanism to prevent data corruption. If a library is locked by one process, other processes trying to access it will encounter this error.
  Long-Running Jobs: If a job is taking a long time to complete, it may hold onto the library longer than expected, causing other jobs to fail.
  
  
  Solution:
  
  Check Running Jobs: Use transaction codes like
