SRM PO Goods Recepient field transfer into ECC

HI,

We are facing a issue which would need your advise. 

We wanted the GR Recipient field from SRM to be passed on the ECC PO.  As this was not standard we put in a code to pass this field value to ECC PO. It works for normal PO.  However, we do not see it passed for a Limit PO & Service POs. 

As we have put in our custom code to pass the field - SAP Support says - this is custom. 

Has anyone else faced the same issue?  How did they handle it?

Appreciate any sort of inputs.

Thanks & Regards
