[anindya_manna]

I want to store the below expression inside the variable.Please help me how to do this.

vAppCondition=((Trim(Schedule)='Daily' or Trim(Schedule)=date(now(),'WWWW')) and $(vFlag_NewProcessDate)=1)or (Trim(Schedule)='Monthly' and $(vFlag_NewProcessMonth)=1)

I am using escape chr(39)to keep the single quote but not working correctly

Under Setting --Variable overview create a variable and add the expression as definition. Then use it in your chart .
