• What is the cause and solution for SAP error message WM605 - Select either tree structure or all material class types - not both ?

  The SAP error message WM605 ("Select either tree structure or all material class types - not both") typically occurs in the Warehouse Management (WM) module when there is a conflict in the selection criteria for material classes during a process, such as inventory management or stock transfer.
  Cause:
  This error arises when a user attempts to select both a tree structure (which allows for hierarchical selection of material classes) and the option to include all material class types simultaneously. SAP does not allow both options to be selected at the same time because it creates ambiguity in the selection criteria.
  Solution:
  To resolve this error, you need to adjust your selection criteria. Here are the steps you can take:
  
  
  Review Your Selection Criteria: Go to the screen where you are encountering the error and check the selection options you have chosen.
  
  
  Choose One Option:
  
  If you want to use the tree structure for material classes, ensure that the option for "all material class types" is deselected.
  Conversely, if you want to select all material class types, make sure that you do not select the tree structure option.
  
  
  
  Re-run the Process: After making the necessary adjustments to your selection criteria, try to execute the process again.
  
  
  Related Information:

  SAP Documentation: For more detailed information, you can refer to the SAP Help Portal or the specific documentation related to Warehouse Management and material classification.
