• What is the cause and solution for SAP error message WT115 - Requirement group data for material &1 blocked by user &2 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WT115 - Requirement group data for material &1 blocked by user &2
  
  Meaning / Cause:
  This error occurs in the Warehouse Management (WM) module when you try to change or create requirement group data for a material, but the data is currently locked (blocked) by another user. The system uses locks to prevent simultaneous changes that could lead to data inconsistencies.
  
  Material &1: The material number for which the requirement group data is being accessed.
  User &2: The SAP user who currently holds the lock on the requirement group data.
  
  The lock is typically set when a user is editing or maintaining requirement group data, and it prevents other users from making changes at the same time.
  
  When does it occur?
  
  When you try to maintain or change requirement group data for a material in transaction codes related to WM (e.g., LS02, LS12, or custom transactions).
  When the system detects that another user is currently editing the same data.
  
  
  Solution / How to resolve:
  
  
  Check who holds the lock:
  
  Identify the user (&2) who currently has the lock.
  You can use transaction SM12 (Lock Entries) to check and manage locks.
  
  Enter the material number or relevant object to find the lock.
  Confirm the user holding the lock.
  
  
  
  
  
  Contact the user:
  
  Ask the user to finish their work and exit the transaction to release the lock.
  Sometimes the user might have left the session open unintentionally.
  
  
  
  If the lock is obsolete or the user is not available:
  
  You can manually delete the lock in SM12.
  Be cautious: Deleting locks can cause data inconsistencies if the user is still working on the data.
  Always ensure that the user is not actively working before deleting locks.
  
  
  
  Retry the operation:
  
  After the lock is released or deleted, try to maintain the requirement group data again.
  
  
  
  
  Additional Information:
  
  Requirement groups in WM are used to group materials for specific warehouse processes, such as picking or putaway strategies.
  Locks are a standard SAP mechanism to ensure data integrity during concurrent access.
  Frequent locking issues may indicate long-running sessions or users not properly exiting transactions.
