Decision table (without nested IFs or Power Query)

Yes, of course.

The decision table reads like this:

• if MulOfVol = 1, then ID 1 (the other parameters are irrelevant in this row, that's why they are empty)
• if MulOfVol = 0 and Custom = 1, then ID 2
• ...
• if SKUCrit01Fail = 1 and SKUCrit02Fail = 1 and SKUCrit03Fail = 1, then ID 5

Based on the fact table, I need to fill in the corresponding decision ID for each SKU.

(I just noticed an error in my decision table, corrected file attached, I'll also correct my initial post).

So SKU1 gets decision ID 1 because MulOfVol = 1.

SKU03  gets decision ID 7 because its parameters correspond with this row (where empty fields are irrelevant).
