Sumif and Conditional formatting ideas

Hello,

I am a beginner to Knime and am looking to use it for a workflow I have in excel.

My workflow uses sumifs to calculate one month’s value of a cost element as a % of four month’s value of the same cost element.

From this the conditional formatting analyses whether or not the 1 month is roughly a quarter of the total 4 month’s value.

If anyone has any ideas on nodes that they think may be helpful with this I would appreciate any steer on this topic.

Thank you in advance,

Sam
