Hi Naresh,
In that case you need to write custom select options in your report .
The SELECT-OPTIONS statement creates a selection table which is basically an internal table that holds the selection criteria for that field.
1. Create two select options as S_PERSA and S_PERNR .
2. Please append all values using Sign,option,low,high inti that select options and after that just delete those enteries which are not required (as per your requirement ) .Now, your selection screen will be filtered !
Try this and revert back if any further information is required .
Best Regards,
