Only permitted infoobjects (not contained infoobjects) transferred: 0fiscper not adding into the infocube

Hi Experts,

While designing a Infocube in BW 7.5 I am able to add all the infoobjects into the required dimensions sucessfully except 0fiscper infoobject in time dimension.

I have added 0fiscper3, 0fiscyear along with 0fiscvarnt sucessfully however while adding 0fisper infoobject I am getting following message.

"Only permitted infoobjects (not contained infoobjects) transferred"

Also when I tried to activate the cube without 0fiscper, it's throwing message " No dimension is assigned to infoobject 0FISCPER, Inconsistencies found while checking infoprovider"

Please suggest the possible reason I am getting the above errors.

Thanks

Shikha
