You can use the function moduele

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

when the user selects the value for the customer number .using that you should populate an internal table

whinch should be passed to next F4 help Function.

In case you need to read a value of another field BEFORE the user hits enter, you can use the following function.

DYNP_VALUES_READ

Then, you can populate the F4 list based on user input of other fields.
