Errors when applying sql expression on filter, please help

Question

Hello guys
I was trying to put a filter on the date column and filter between timestampadd(sql_tsi_day,-31,current_date) and current_date
I was successfully able to define both field on sql expression of the filter and I selected "is between"
However when I run reports it returns the following errors:
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 22024] A comparison is being carried out between non-compatible types. (HY000)
SQL Issued: SELECT "Year"."Transaction Date" saw_0 FROM tranSale_cube WHERE "Year"."Transaction Date" BETWEEN timestampadd(sql_tsi_day,-31,current_date) AND current_date ORDER BY saw_0
When I using the same timestamp expression on the column formula and run report without filters, the report will return the correct date however though
I am using essbase as the data source.
Please help
Thanks

Thanks
However, the error still exist the same.. This error code returns when I run report based on this one single column
when I put this date column with measures and other columns then run report, I get a different error:
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 42043] An external aggregate is found in an outer query block. (HY000)
SQL Issued: SELECT Product."Brand Name" saw_0, "Up Level"."Trial - level 12" saw_1, "Year"."Transaction Year" saw_2, "Year"."Transactoin Month" saw_3, "Year"."Transaction Date" saw_4, tranSale.count_of_transactions saw_5, Avg(tranSale.count_of_transactions by "Up Level"."Trial - level 12", "Year"."Transactoin Month", Product."Brand Name") saw_6 FROM tranSale_cube WHERE ("Up Level"."Trial - level 12" IN ('0', 'Product Upsell')) AND ("Year"."Transactoin Month" >= '2009 Feb') AND ("Year"."Transaction Date" BETWEEN timestampadd(sql_tsi_day,-31,current_date) AND current_date) ORDER BY saw_0, saw_1, saw_2, saw_3, saw_4
I believe it must be something with the essbase that is not serving OBIEE well. Because I tried the same filter on a different environment not having essbase, it return me the right results..
Could anyone help?
Thanks
