Something like this?
DECLARE @MinPeriod intSELECT @MinPeriod = MIN(a.period)
FROM agr.dbo.atrans a
CROSS APPLY (
SELECT CutOffTid = ISNULL(MAX(ccas_id),0)
FROM dbo.fbs_trans
) x
WHERE a.agrtid > x.CutOffTid
As Chris said, and then just wrap that in a CREATE PROCEDURE with @MinPeriod being a parameter. Should be fine. If not, ask your DBA for an execution plan, and we can evaluate further.
