Cannot adjust beneficiary advances against this payment document

What causes this issue?

This payment document contains one or more expenditure orders with a
source other than material management. Beneficiary advances can be
adjusted only against expenditure orders with source material
management.

System Response

The system does not allow you to adjust any beneficiary advances against
the payment document. However, you can still post the payment document
without adjusting any beneficiary advances against it.

How to fix this error?

To adjust beneficiary advances made for a purchase order, create payment
documents for expenditure orders that have source material management
and that correspond to the same purchase order.
For example, if EO1 and EO2 are expenditure orders with source material
management and EO3 is an expenditure order with source finance invoice,
then create two separate payment documents - one for EO1 and EO2 and one
for EO3. Then you can adjust the beneficiary advances against the
payment document for EO1 and EO2.
