Move Equipment custom fields from ECC to CRM

Hi guys,

We have a requirement where I need to move some fields from ECC to CRM(in set type), for which I am using method IF_EX_CRM_EQUI_LOAD~ENLARGE_SET_TYPES of BADI impl. CRM_EQUI_LOAD_STDIMP.

All of the posts on the internet say to enhance BAPI_EQUI1 on both sides but this structure is not enhance-able by SAP.

I just want to create some Z-fields in BDoc structure, populate them in ECC side and use them in CRM.

Please Help!

Thanks,

Harsh
