IR created for Purchase order without accounting document

Hi all,

We have a peculiar situation where an IR (Invoice receipt) document has been created for a purchase order where the corresponding accounting document has not been generated. Can you please let us know how can we create accounting document for this IR.

We tried to reverse this IR by transaction code MR8M but it is throwing the error message "Reversal not possible, accounting document for the ref. does not exist".

We understand that there is some standard SAP utility which posts the accounting document and in case there is some configuration also for this, please let us know.

We would be grateful for any information on resolving this issue.

Regards,

Santosh
