Hi Sohail,

Your scenario

2 sel screen params

both have 2 search helps

You can use this FM

F4 help also returning the value to be displayed in internal table

F4IF_INT_TABLE_VALUE_REQUEST .

What you do is as soon as the user gives value in the 1st sel screen params,fetch it in an internal table,suppose int_tab_selscreen1 use this internal table in the I_tab field of the above FM.

What happens now,

as soon the user enters value in the 1st sel screen params, it is stored in an internal table,

now the user enters values for the 2nd sel parameter,

since we are using the above function module, it will have an internal table field (in our case its the int table having values entered in the 1st sel screen param)

hence your issue is solved.

Hope you have understood the solution

Revert for further clarification.

Thanks and Regards
