Problem with Import package!!

Hi Experts,

I am creating a new import package in BPC 7.5 M and giving DataTransferMode property value as "1" (Import into SQL) of Dumpload task and RUNTHELOGIC property value is also 1 so it means it should run default logic,Now the problem I am facing is that default logic is not running at this time but if i change DataTransferMode property value as "4" (Import into cube) then default logic runs fine. So I would like to confirm that is there any rule defined that when we use DataTransferMode=1 then default logic will not run.

Please help!!

Thanks & Regards,

Rohit
