MIRO Error - Specify Payment Period Baseline Date

Hello all,

When attempting to post an invoice in MIRO I receive the error "Specify Payment Period Baseline Date", however no matter which date I select, when I attempt to post the invoice the field is cleared and the same error message is given.

I have maintained Payment Terms in the vendor master and have tried changing the default for baseline date in OBB8 and I am still receiving the error.

I have tried using different payment terms as well and still receive this error for all payment terms.

Any help appreciated,

Casey
