Datasource has no up to date data

Dear SDN,

I have a Z report in R/3 side.The requirement was creating same report in bw side.

For this,i created a view with same fields on Z report then replicated on bw side,created all transformation and report.

Report results were completely matching with Z report everything was ok but two days after i noticed that on bw side there is no update.

When iu2019d like to reschedule infopackage as full update there was no new data belongs to last 2 days but on R/3 side i have update data.

Am i missing something?

Thanks
