Replication of custom field from CRM to Ecc

Hi Every one,

I am facing a issue,My requirement is that i have to create Iobject and business agrement and link between both while creation of Business partner and this should reflect to the ECC system.

All its happening fine,Now we have added two extra field in CRM BP_ID and Case_id using Set Type in Iobject and filling these value while creation of link between  Iobject and business agrement using code.

Every thing working fine in crm side.

In ecc we have enhanced the table DPSOB_BP_ACC to capture the value BP_ID and Case_id .I am getting the value in ecc side i checked while debuging the middle ware,Now please let me how will i map these value so it will store the value BP_ID and Case_id in  table DPSOB_BP_ACC

Note-Creation Iobject, business agrement and link between both of them all its happening with the code in CRM side

Thanks and regards,
