I have a list of SKUs and their associated revenue - one of these SKUs I'd like to split into 4 *new* SKUs whose total sums to the value of the original SKU; see the screenshot below, highlighted in yellow.
The splitting of SKUs isn't conditional on any other field. I was envisioning I could write a formula or sorts where, for example
IF [SKU] = IST1 THEN [Revenue] * 0.25 (IST1-A)
ELSEIF [SKU] = ISTS1 THEN [Revenue] * 0.5 (IST1-B)
However that doesn't quite work. Any ideas?
