Purchasing document not yet released- Flexible standard workflow

Any help is highly is appreciated

Hi Guys,

Since we activated Flexible workflow for Purchase Order every purchase order is getting error "Purchasing document 45XXX not yet released" and no workflow is triggered. (as there is no active workflow)

The only flexible workflow active is Standard SAP out of the box "Automatic Release Of Purchase Order". I believe this workflow should release all purchase order automatically without approval. Basically, now every PO is 'stuck' as neither a workflow triggered nor PO can be Goods receipted.

I even tried deactivating SAP out of box workflow but no luck.

Appreciate your help,

Thanks
