Problem in Complex Table drop down

Hi Friends

we have Requirement to show a complex table dropdown in Add Transaction in Service Manager. we made changes in Agentry as well as Backend and it showing values in Complex Table drop down.

This complex table drop down is in Add Service order Transaction screenset.

But it is displaying only one entry [first value] whereas backend has more than 80 entries. In complex Table dropdown, I want to display Date, other fields are Service Order id and item number

I have added an Complex table drop down seetings as

1. Date (Index 1)

2. Service order id (index2) Parent index of Date

3. Display Field (date)

4. Return field (Date)

I changed different settings in Indexes. But still only one value coming in dropwdown.

Am i missing anything ? Please help me.
