Hello

I have reviewed the new AP attributes but it seems none of the if for the new PO "Rate Base Services".

I raised a PO with the line type "Rate Base Services" and I inquiry the AP_Invoice_Lines table and the value is "ITEM_TO_PO". Although I setup the BPM Approval rule is error out. Hence I was wondering if you can share with me any AP invoice rule for the PO line type = "Rate Base Services"
