Table join between PA0001 and CATSCO

Hi Experts,

I am working on a report and want to select only those employess who entered time (CATSCO data ) based on work date which is a select option on selection screen and i want to filter them based on personnel subarea ( PA0001-BRTL) on selection screen.

Below is my select query:

select fields from pa0001 and catsco inner join based on pernr

CATSCO-WORKDATE in s_workdate

PA0001-SUBAREA    in s_subarea

PA0001 has 5 entries for a pernr and subarea on selection screen  and it fetch all of them .

CATSCO has 3 entries for pernr and given workdate on selection screen and it brings all of them.

I am expecting the query to pick only 1 entry from PA001 based on subarea and workdate on selection screen but i dont know how i can use

ENNDA and BEGDA based on workdate on screen.

Can someone please suggest?
