Vijay,

It should work with on value request .

In example

select-options : p_regio for t001w-regio

no intervals, "Region

p_werks for t001w-werks

no intervals. "Plants

at selection-screen on value-request for p_werks-low.

perform f_f4_help_for_plant.

when action in selection screen is performed the region value will be stored in p_regio and hence available for query for plant .

Check that and let us know

Hi Vijay,

The best option is to create a search help for these three fields, but the pre-requisite being they should come from the same table. If they are not from same table create a view for them, preferably a Help view and create a search help.

Attach the search help created at the field level, and do not use VALUE-REQUEST event in the program as it takes precedence over search help.

Please let me know if it works or further details are required from my side.

Goutham.
