BADI MRM_CHECK_INVOICE_CLOUD can be used to perform customer specific checks of header and item data when creating supplier invoice. When you reverse a supplier invoice it also can be called and perform custom check.

But please note when you create supplier invoice the BADI is also triggered to ensuring that the invoice created will always meet your validation criteria. So I understand there should be no need to check it again when reversing invoice.

You can refer to this online documentation about all available BADI in supplier invoice for your information:
