Can we do Map for OM Header EFF to AR Line DFF

Hello Experts,

We have a requirement where the OM Header EFF (Base Price) needs to be populated in the AR Transaction Line DFF.

From my understanding of seeded service mappings:

• OM Header → AR Header is supported
• OM Line → AR Line is supported
• OM Header → AR Line does not seem to be supported

Has anyone implemented a solution for this? Specifically:

• Is there any delivered way to map OM Header EFF directly to AR Line DFF?
• If not, what is the recommended approach — replicating the Header EFF to OM Line EFF, or enriching the payload through OIC before invoice creation?

Any guidance, confirmation, or best practices would be greatly appreciated.
