Filter in webi report after conversion from deski

Hi All,

SAP BO 4.1 SP7

I have a deski report with filters, new data is load into this report every Wednesday.

The weekend date starts on Saturday, so today's load date was 4/2/2016

l converted it to webi and all filters where remove, which is OK.

In Webi l add the filter into the report but when l refresh  does not change the date with the filter

when filter is remove the previous week date is show.

Note: when l refreshed the deski report it populate the date 4/2/2016

when filter is remove and report is refresh date show 4/2/2016

When filter is added  and refresh no date is populated

Please any solution out there

Thanks
