I have set up scheduled imports of various tables from a master Excel spreadsheet to perform various Zoho Analytics functions.

The problem I have is that if I make any changes to the structure of the source spreadsheet, Zoho Analytics stops importing the mapped tables - even if I have not made any changes to those specific tables. 

This issue is compounded by the fact that there is no indication of the import having failed - the Zoho Analytics source data just stays as it was on the previous successful import so I don't see a flag to tell me that there is a problem. 

The only way I can avoid this is to remap all imports each time I make any changes to the source spreadsheet. Can you fix this issue?
