BAPI BAPI_CONTRACT_CREATEFROMDATA Question

Hi,

Is there a way to add field VBKD-TRATY in the BAPI? I'm using BAPI_CONTRACT_CREATEFROMDATA to copy sales contract into a new one but since that field is not available in BAPISDHD1 header structure, it is not being copied.

What would be the best way to do this? Points will be rewarded.

Thanks,

Gene
