Text in Bex analyzer is giving problem

Hi Experts

i have two issues with my Bex analyzer, RSRT and Portal

1. i have report which has Project code and its description (text) when i am runing this report for some project codes the text is not displaying instead it showing space, if i go to that particular project and say keep filter value and select only that value then its showing the text in that column...what could be the reason.

2. i have created variable for my report its displaying perfectly in bex analyzer but in rsrt and web portal...the variable screen is getting ignored.

what could be the reason.

thanks and regards
