• What is the cause and solution for SAP error message WM396 - Material & is already assigned to & as rack jobber material ?

  The SAP error message WM396 indicates that a material is already assigned to a specific location as a rack jobber material. This typically occurs in the Warehouse Management (WM) module when there is an attempt to assign a material to a storage location or perform an operation that conflicts with its current assignment.
  Cause:
  
  Existing Assignment: The material in question is already assigned to a storage location as a rack jobber material, which means it cannot be assigned again to another location or operation without first removing the existing assignment.
  Configuration Issues: There may be configuration settings in the WM module that are causing conflicts with the material's assignment.
  Data Integrity Issues: There could be inconsistencies in the master data or transactional data related to the material.
  
  Solution:
  
  Check Current Assignments: Use transaction codes like LS03N (Display Material) or LX03 (Display Stock Overview) to check the current assignments of the material. Verify if it is indeed assigned as a rack jobber material.
  Remove Existing Assignment: If you need to reassign the material, you may need to first remove the existing assignment. This can typically be done through the appropriate transaction (e.g., LT01 for creating transfer orders) or by adjusting the material's status in the system.
  Review Configuration: Check the configuration settings in the WM module to ensure that they are set up correctly for handling rack jobber materials.
  Consult Documentation: Refer to SAP documentation or help files for specific instructions on handling rack jobber materials and their assignments.
