Link Original Invoice from Supplier BN to SAP S4 MIR4 GS attachment

[Anup_S]

We have enabled the feature NP-36965- NP-36965: Support for Marking an Invoice Attachment as the Original Invoice. In the Integration gateway we have updated mapping to pass originalInvoiceAttachmentCID the name of original marked attachment from Ariba Supplier BN.

Now we are looking for the ABAP Code to update this file name as original invoice in MIR4 GS attachment list from the IDOC FM IDOC_INPUT_INVOIC_MRM in SAP S4 HANA. There should be a placeholder updating the file as original invoice from Supplier as supplier would be attaching many different attachments.

If anyone has implemented any similar solution, please share your ideas
