• What is the cause and solution for SAP error message WM750 - Material &1 locked by assortment functions being performed by user &2 ?

  The SAP error message WM750 indicates that a material is locked due to assortment functions being performed by another user. This typically occurs in the context of warehouse management (WM) or inventory management when one user is executing operations that affect the material, preventing other users from making changes or performing certain actions on that material.
  
  Cause:
  
  Concurrent Access: Another user is currently performing assortment functions (like creating, changing, or deleting assortments) on the same material.
