Can you please include a screenshot with your "Final Shipping Time Weeks" line item? It looks like you are comparing it to your "Shipping Time Weeks" line item in your screenshots, which has 1 as the value, but your Final line item might have some other value and this is what you are including in your formula.
a) Confirmed PO Delivery = OFFSET(PO Submitted, -Final Shipping Time Weeks, 0)
b) Confirmed PO Delivery Test = POST(PO Submitted, Final Shipping Time Weeks)
With the above formulas, the results are as in Diagram 1. Am trying to understand why Confirmed PO Delivery is in Week 6 instead of 7 or is it supposed to be in Week 6. Essentially, am trying to understand the difference between OFFSET and POST.
It will move to Week 7 if the formula is changed to OFFSET(PO Submitted, -Final Shipping Time Weeks - 1, 0) -> Diagram 2
Post and Offset are very similar functions, however, they are going to give you very different results. Offset is going to give you the value from your selected line item x number of periods in the future or in the past. For example, in your line item Confirmed PO Delivery, week 6 is looking back 1 period (Final Shipping Time Weeks = -1) and resulting in your value of 1 since there is a 1 value in Confirmed PO Delivery in week 5.
Post, on the other hand, is going to push the value from your selected line item x number of periods in the future or in the past. For example, in your module, the 1 value in week 5 in your Confirmed PO Delivery line is being pushed 2 periods into the future because that is value in your second argument in your function (Final Shipping Time Weeks = 2). This function also allows you to sum values if they point to the same period. For example, if you also had a 1 in the Confirmed PO Delivery line item for week 6 it would be pushed forward 1 week into your week 7 and combine with your 1 value from week 5 to give you a value of 2 in week 7. Offset will not let you combine values in the same way.
I am trying the formula "IF PO Submitted > 0 THEN POST(PO Submitted, Shipping Time Weeks) ELSE 0" for the confirmed PO delivery? However, the week3 value for confirmed PO delivery is not getting changed. can you please help me in this ?
I am trying to figure out if there is wrong in the below formula for Confirmed PO delivery. I am facing an issue where after applying the given formula, the desired value is not getting populated in the confirmed PO delivery line item.
"IF PO Submitted = 1 THEN POST(PO Submitted, Shipping Time Weeks) ELSE 0"
