In BAPI structure AET field is not available

Hi,

I have created one field through AET, I has been created under BTAdminH context and table name CRMD_ORDERADM_H.

I want to create FM, which creates the service order along with the new field which is created by AET, Here new field declared as import parameter. So i am going to call FM BAPI_SLSTRANSACT_CREATEMULTI in my Z FM.

Here the problem is, i am not able to see new field in above FM parameter structure HEADER    LIKE    BAPIBUS20001_HEADER_INS.

But new field is available in CRM_ORDER_READ and CRM_ORDER_MAINTAIN FM structures.

So to create service order along with new field data, is there any other function module, which have AET fields structures ?

Please help me with your valuable answer

Thanks.
