How to Sort a Classic Badi?

Hi Friends,

Can you please guide me how to sort a classic BADI.

Below are the steps I followed:

I created a Badi implementation in the BADI (BADI_LAYER) and included the Badi (BADI_MATERIAL_CHECK) which should be sorted . A subscreen with field FLT_VAL was created and passed to the implementation.

When i try to create an implementation for BADI_MATERIAL_CHECK a new input field for filter value is displayed, but the sorting is not working as expected.

Please help me to resolve the issue.

Will be rewarded !!!
