The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check whether a suitable certificate exists for the purchase order and
delivery, and create a certificate record with the status "Certificate
checked and stored".
If there is no certificate or no suitable certificate, this does not
comply with the requirements in the material master record. If there is
no inspection lot for this goods movement, the system posts the
quantity to blocked stock or does not post the goods receipt.
If you have created an inspection lot, the system marks the certificate
check with the status "In lot". You must confirm the availability of an
inspected certificate by the time you make the usage decision.
