You can use FM 'DYNP_VALUES_READ' to read the value entered by the use in any field of the selection screenby passing relevant paramters. Then depending upon the value of the field you desire, you can appropiately fill an internal table and call 'F4IF_INT_TABLE_VALUE_REQUEST' to display the desired list.

Hi,

I suppose you have a ztable with fields including dep_city and dep_airport. Then you need to have an elementary search help for the respective field created by you with the structure of your table.

In layout you select your field and in name field you give your table name and the field name(ztable-dep_airport). Now in attributes you give search help name you created for the field.

It may work i am not sure.
