2. Convert the PR to a PO using the app 'Create Purchase Order - Advanced'
3. In 'Create Purchase Order - Advanced' switch on the Document Overview.
4. In the Dynamic filter section enter the WBS Element from the PR created in step 1 and execute the search.
5. No data satisfying selection criteria exists (Message no. MEQ009).

Standard system behaviour.
When selecting Purchase Requisitions using the 'Selection Variant', searching can be performed with purchase requisition fields, specifically fields that exist in the EBAN table. 
The WBS Element visible in a Purchase Requisition is held in the account assignment table EBKN which is not used here. 

*The 'WBS Element' field available in the dynamic selection, concerns the field EBAN-DISUB_PSPNR. This field is generally not filled and is specific to the Industry Solution for Aerospace and Defense. If Industry Solution for Aerospace and Defense is used, then the WBS Element field (EBAN-DISUB_PSPNR) will work as dynamic filter for purchase Requisitions  

1. Search for purchase requisitions using filter criteria from the purchase requisition item CDS view I_PURCHASEREQUISITIONITEMAPI01 (table EBAN) 
2. App Display Purchase Requisitions (ME5A) can be used to identify purchase requisitions using the 'WBS element' field from the account assignment CDS view I_PURREQNACCTASSGMTAPI01 (table EBKN)
