Delete button greyed out in All Purchase orders mask for one order. The approval status is draft while the status is open order with delivery remainder zero, or cancelled if I use the cancel button at the top menu. The purchase order has a purchase order workflow, and the workflow is not initialized, because if I press the workflow button it only contains the option /submit/. There are no confirmations or product receipts it seems. I need to either delete it or explain why it only can be cancelled. Where can I find a record of a relation or something open which could explain this?. No pending workflow or with errors in the workflow history. Please your help, any information is welcome. Thanks a lot!
