Problem in uploading rectification u/s 154 to cpc through e-

Although what's the exact problem will be understandable after seeing the actual position. however i think there are a common by most of the cases while filling rectification and got errors:-

Like if your CPC Communication Ref no is CPC/AB45/I4/1234567

In this case there is a word I4 and not 14. There are such type of common errors which needs critical review.

However as per my expreience if the systems generates the error than there must be some mistake from your end. Review it again carefully.
