Invoice price variance is too important to save the invoice

Dear Gurus,

I have currently in the process of creating an invoice through MIRO with a negative price variance of 5€ for a purchase order of 100 without taxes. When i try to save it however, a M8534 message pops that tells me the price difference is too important to save the invoice.

I checked the PP tolerance key in OMR6 where all limits are set on "do not control" except for one: superior limit, which is set at 10.

Any ideas where else I could look to be able to save the invoice?

Ps: I am new to SAP, please refrain from throwing short, mysterious messages with one transaction code and a mystic comment like "check the arboresence for misplaced TS". Thanks 😉
