3370347 - The item category is not allowed for the purchase order document type - migration object: "MM - Purchase order (only open PO)"

You have SAP S/4HANA Cloud 2308 system. - You are using the Fiori App "Migrate Your Data", and you encounter an error during simulation or migration of "MM - Purchase order (only open PO)" object.

The error message logged is DMC_RT_MSG 0 - The item category is not allowed for the purchase order document type <XY>.

This issue occurs when the item category field in the migration template is left empty, indicating a "Standard" category.

1) Open Migrate Your Data Fiori App.
2) Select migration object "MM - Purchase order (only open PO)".
3) Start the desired action (Simulation / Migration).
4) In the Monitoring, you can see error message in the log of the performed action: The item category is not allowed for the purchase order document type <XY> - DMC_RT_MSG 0 .

The permissible Item Categories are set by the Materials Management (MM) customization. The system compares the inputted Item Category (which is blank, hence defaults to "Standard") with the pre-set list of acceptable Item Categories. Here, the "Standard" item category is represented as "0".

Therefore, the mismatch - "Standard" (blank input) versus "0" (system coding for standard) - triggers an error message. The system is confused because it expects the "Standard" item category to be represented as "0", not left blank.

As temporary solution (workaround), on the "Item Data" tab of the migration template instead of blank Item Category, please fill the Item Category as 0.

Permanent solution  we have completed a correction/addition to your software.

This correction is planned to be delivered with Hotfix Collection 05

The implementation is planned to take place in the next maintenance window at the  September 17th.

This is current state of planning and may be changed by SAP at any time without notice.
