Table Maintenance

[Former Member]

The requirement is, I have 3 fields on the screen. User provides the inputs in first 2 fields.

Now, I would like to search the possible values for the 3rd field based on the values entered in the first 2 fields.

On the search help I have 3 fields. Here, I have to default the first 2 fields with the values entered by the user in the first 2 fields on the

screen. I know that I can do it in the PRESEL callcontrol-step, but the problem is I am not able to capture the values of the first 2 fields from

the screen

I have written the code to show the F4 help in the POV event of the screen generated by table maintenance generator. I am not able to capture the values of the first 2 fields using DYNP_READ_VALUES. And I want the values of the first two fields to show the f4 values for the third field using a select query

Please help me out here.
