Miss Matching with GSTR-2B and Tally

GST Present Rules >>>  If ITC not reflected in GSTR 2B then Credit Not Allowed 

 Example :  For  December  >>> Input Bill is entered in Tally . But Said Bill Not Reflected 

at GSTR -2B ---. And  This is bill is Reflected  in GSTR-2B  on  Jan 

( Practically Input Bill is related for Factory Raw Material Stock Account 

and have to entry in Tally for December )

Question : How to maintain in Tally for above situation ????

Please Reply ... thanks
