Hi All
In Inter Company STO, after saving the IC billing document using RD04, the MIRO gets created automatically using the Inbound IDOC. This functionality working fine.
Now the requirement is after saving the IC billing document, in VF02 business attach some documents in the billing document, so that attachments should be reflected in MIRO which is created automatically using RD04 inbound IDOC.

Please let me know how to achieve this. Is it something need write some code Inbound FM which creates MIRO?
Other Information: Tried to check using RD04 standard functionality whether attachment is showing in MIRO which is created using Inbound IDOC( RD04) but it is not showing those attachment which was attached in VF02( IC Billing doc). and client is using SAP S4 Hana 2021
Thanks
Srinu
