Need to pass email field(SMTP_ADDR)while creating the vendor using CREMAS

Hi All,

i am creating the vendors by IDOC by using CREMAS basic type CREMAS05.

There is no email field in any of the idoc segments,as i need to pass the email address being mandatory,

i created the Z segment and added the email field into it and then created the z extension and added this zsegment into the extension.

Now how do i and where do i map this field so that email data is also passed while creating the vendor master.

i have debugged the cremas Function Module IDOC_INPUT_CREDITOR and the data is getting passed segment wise,and for customer segement i.e for the zsegment there is a enhancement section where i need to pass this field,but i do not know how do i map this field and with what structure.

Please let me know how do i handel this/or is there in other way to do it.

Thanks.

RJP.
