reporting services - SSRS Report Parameter Available Values setting -


i trying set available values on ssrs report parameter properties. wish can add images not enough reputation.

when select 'get values query', don't have problem. however, message when trying use 'specify values'

"field cannot used in report parameter expressions."

i using following expression. appreciated.

=first(fields!eventcode1.value, "history2")

you cannot use same dataset "history2" field (column in report design) , in parameter list. create different dataset required value , use in parameter.

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
