• What is the cause and solution for SAP error message WW064 - MG material & is already being edited ?

  The SAP error message WW064 indicates that a material (in this case, a "MG" material) is currently being edited by another user or session. This can occur in various transactions where multiple users might attempt to edit the same material master data simultaneously.
