Error in Reports While opening

Hi Freinds,

for some the reports while opening in change mode I am getting error " An unexpected 'assertion: rbselection::fromtable - missing dkf in xref: 4axot77dyhrjz7s6bm5y9rdxj - 4axoh8mj2sv5vpk78axmnncxz' error occured in wdbrlog." and it is disconnecting from SAP.

But other report which has build in same InfoProvider is working fine.

Could you please suggest how to resolve this.

Thanks & Regards

Shalini
