Requisition charge account generation fails with deliver to location

hi all

I am creating both internal requisition and purchase requisition, which are failing due to a charge account generation error. The error is very generic but suggesting that the combination is an invalid combination?

if I delete the deliver to location, the charge account generates or regenerates with expected value, depending upon where I delete the location. however, I know i cannot submit the requisition as the deliver to location is a required field for the requisition.

For the internal requisition the locations created are linked to the inventory org in the location setup

for the purchase requisition the locations created are linked to the operating unit
