Sorting List of Values in F4 search for Query Variable

Hi All,

We have a requirement to restrict no of values in descending order for Calender Year on F4 help in query execution. I have implemented BADI RSR_VARIABLE_F4_RESTRICT_BADI to restrict values appearing but not able to sort the final output. I checked and found that sorting is being handled through  class CL_RSMD_RS_SPECIAL over the restricted values in BADI.Can anyone help on how to achieve sorting for final output of F4 healp.

Thanks in advance.
