Go to SE51..Give the program name..in your case..SAPL + function group name.

Give the screen number...that you gave when you created the table maintenance..

THen press change..

Create an event process on value-request for F4..

PROCESS ON VALUE-REQUEST.

FIELD ZTABLE-F4 MODULE F4_FOR_F4.

**In the module use the function module F4IF_INT_TABLE_VALUE_REQUEST.

Check this example for how to use this function module

You will have to create a data element and domain for your table fields to get the F4 values in table maintenence...

Define your possible values in the domain.

Once you do this, you will have the f4 values populated accoring to the domain you have defined. .
