Hello,In my old report I got something like thisSELECT MIN(cast("ParDyn"."ParVal" as integer))FROM "result".ParDyn WHERE "ParDyn"."ParNo" = (SELECT Max("Piece"."ParDynNo")                          FROM "result"."Piece"                           WHERE "Piece"."RequestNo" = XPARAM1 And "Piece"."PieceNo" = XPARAM2)      And "ParDyn"."ParIdent" = 'Trace.Assignment'  This report are viewed from VB component - at old VB they read SQL from report, input XPARAM1 and XPARAM2 and put it into report again and the show report.Because now I want to make my aplication I convert this report to use it not only at this old aplication, but with CR Viewer too.I see I can not insert Parameter into SQL Statement, so I need to use Basic or Crystal Formula.I try to make something like this : minimum({ParDyn.ParVal})and {ParDyn.ParNo} = 0of cource zero should be exchange with next statement, but this not working.What I would like to get is only one record, I do not want get whale table into CR engine and then evaluate becouse this report must work on slow connection, so I need take from database only records witch I need. Can someone help me, or show how to insert into formula value as parameter taked from another table dynamicly ?? Best Regards Bartłomiej Jóźwiak

Ok,
The only way I found to get the maximum status date of an employee with the date entered in parameter was to litteraly put each employee ID, and Status Date in the Detail section.
Then in the select expert create the parameter date.
Then I created a running total field that counts the employees and resets on change of employee sorted by status date.
Then I created a formula that gets all the first occurences of this running total field and if the running total field equals 1, a new formula field shows 1 and if not (2 and more), it shows 0.
But I can't find the way to give me the total that I need for each group sections.
It's ok if the SQL expression field does not work, but I need to find a way to get the max date.
Thank's for your help for the SQL Expression field.
