HR related query

Hi experts,

i am developing report.

requirement :

on selection-screen there are select-options.

1) Personnel no

2) Employee name

user can choose either of them.

now my query is when i select personnel no, report shows correct output in Script.

if user enters value in second select-option lets say a* then report should pick up all the values and to display in Scipt.

since this report is built using HR-ABAP concepts. i am finding difficulty in writing code.

how to get the values related to the employee using macros.

any sample code??

thanks in advance.

Saurabh.
