How to get single vale from each context

Hi Guys,

I have small problem in mapping.

I am getting an output as shown below

SUPPRESS

123456

456789

SUPPRESS

123456

456789

SUPPRESS

123456

456789

SUPPRESS

123456

456789

SUPPRESS

123456

SUPPRESS

123456

SUPPRESS

In each context, i should get only one value as an output.

If have only 1 value then there is no problem (see the last 2 contexts)

Could any one help me how to get this.

Thanx

Kumar
