DDLB missing in AET fields after transport

Hi SAP family,

I came across a weird scenario in CRM sales application.

I added  custom fields in "opportunity ' business transaction using AET..

These fields are ddlbs(picklist) .

When I moved the Transport requests to target system, fields are appearing without drop down.

In configuration fields are shown as drop down  and the coding for V-getter and P-getter methods are in place.

I did not know where I went wrong..

Please let me know your ideas.

Thanks & Regards
