Using IF statement to substitute column values

[manojdawson]

Hi

I need to substitute blank values in column "January Estimate" with the value from "6m Avg" every time On Promotion is "N" and January estimate is "." But for On Promotion "Y" it should retain the same value in the estimate column

ProdCode	LongDescription	QtyOnHand	On Promotion	January Estimate	6m Avg
1111	XXX	54	Y	72	18
222	YYY	33	N	.	16
354656	ZZZ	52	Y	61	16

How do I do it?

Thanks

You need to show example data that captures both conditions and, for clarity, what you want the resulting file to look like. I, personally, would also like to see you propose code to solve the problem.

Hi, please try the below code , However i agree with Art , if you provide more details then you will get the more appropriate response.

i just tried with a simple if then statement. Hope this helps.

data want;

set have;

if OnPromotion='N' and JanuaryEstimate eq . then JanuaryEstimate=_6mAvg;

run;

Thanks,
