BEx Filtering

Hi,

Currently i have requirement in the BEx reporting

In my reporting layer DSO has 2 types of date, lets name it Date A and Date B.

So whenever the user enter the date in the selection parameter,

If the "date = Date A" OR "date = Date B", the records will be displayed in the report.

I understand that the SQL statement generated by Query Designer will be AND statement.

Anyone has some idea or work around ?

Thanks.
