Annual financial report

So I was checking few company annual report,where I found previous year cash flow isn’t matching in current year.
Like every annual report have two year cash flow,the year and the previous one. So the share I was looking, every annual report have mismatch data of previous year
I had checked for 4 to 5 year same mismatch I had found.

Can any one explain why company do so?

Which company? Which year’s annual reports are you comparing?, did you cross check with screener.in ?

Download from BSE website and compared year after year for multiple time. And satia industry and refex industry are the share I am talking about.
Satia have it for every year,
But refex have change for single year.
Compare last 3 to 4 years of both companies
