Linking a PO (BUS2012) to its corresponding RFX response.

Hi guys,

Is there a direct way where I can link my PO, ECC created (BUS2012) to it's corresponding RFX response?

I am to create a table where all the PO's listed will have it's corresponding/originating RFX response.

I have tried the FM BBP_PD_PO_GETDETAIL but as per my research, it is only for PO's created in SRM (BUS2201).

Many thanks!
