Formula to compare 4columns with differences & to produce summary of differences on she2

[JEAN1972]

Hi

See annexed need to compare column C.F,G,I.
Column C represent productCode.

Column F represent % of Tax

Column G represent the code Classifcation for applicable tax %

That is column F and G are related.

Column I represents suppliers.

What I am expecting is to compare these columns mentioned above and to hightlight differences in these columns and produce a summary of differences to sheet 2 with their respective headers.

Note the record reads 30000 rows .

I have highlighted in red sample as diffrence to be more explicit what I am expecting .


Thanks in advance for those who can help to solve.
