QUESTION
I have a sheet where I entered all products that I have bought in year 2021. This is on Sheet1.
On Sheet2 I want to get listed unique products (that I have managed to do) and how many of each unique product I have bought inside the country (home) and how many I bought outside the country (abroad) and how many I bought together outside and inside my country.
I got some numbers as a results of trying with different formulas but then I wanted to see if the results are correct and everything stopped :(
basically should products bought abroad plus products bought home equal to total product bought.
At the end I decided to use the query formula to achieve my goal because it is most easy to understand due to the similarity of its select statement to english language.
So, I composed these 3 formulas:

QUESTION
I am given the following sales table which provide the sales that each employee made, but instead of their name I have their ID and each ID may have more than 1 row.
To map the ID back to the name, I have a look up table with each employee's name and ID. One thing to keep in mind is that any given name could potentially have more than one ID assigned to it, as described in the example below:
Sales Table:
Year ID North South West East 2020 A 58 30 74 72 2020 A 85 40 90 79 2020 B 9 82 20 5 2020 B 77 13 49 21 2020 C 85 55 37 11 2020 C 29 70 21 22 2021 A 61 37 21 42 2021 A 22 39 2 34 2021 B 62 55 9 72 2021 B 59 11 2 37 2021 C 41 22 64 47 2021 C 83 18 56 83ID table:
ID Name A Allison B Brandon C BrandonI am trying to sum up each employee's sales by a given year, and aggregate all their transactions by their name (rather than ID), so that my result looks like the following:
Result:
Report 2021 Allison 258 Brandon 721I want the user to be able to select the year, and the report would automatically sum up each person's sales by the year and their name. Again, Brandon was assigned ID B and C, so the report should be able to obtain all 2021 sales under B and C.
I posted a similar question which did not include the added complexity of having a name tied to more than one ID. In that thread, I was provided a solution with the following formula:

QUESTION
The issue I am having is trying to use XLOOKUP on a table column that has been generated using a ranking formula.
The Rank column is created using the following formula so that it adjusts dynamically depending on the visible columns (auto-filtering) since RANK.AVG or EQ does not take that into account.
...ANSWER
Answered 2022-Mar-04 at 08:55You'll need to employ a similar construction to account for visible rows only, for example:
=LOOKUP(1,QUOTIENT(0,SUBTOTAL(3,OFFSET(INDEX(Table2[Sales],1),ROW(Table2[Sales])-MIN(ROW(Table2[Sales])),))*(Table2[Rank]=1)),Table2[Rep])
Not sure why you're referencing the table header row in your other formula.

QUESTION
This is the same problem as (Excel: SUMPRODUCT calculating shared workload in hours with percentages) with an addition.
I'm trying to calculate the workload/hours for each employee for certain projects. In column B you can see the responsible (100% of the workload), in C you can see which employee is taking 50% or 25% of the workload off the responsible employee. So I need the sum of all hours, while deducing of adding the 50% or 25% in case the workload is shared and giving it to the employee helping.
The latest formula adding/subtracting only the 50% in C:
=SOMPRODUCT(($A6=$B$2:$B$5)*($B$1-$C$1*(""<>$C$2:$C$5))*E$2:E$5+($A6=$C$2:$C$5)*$C$1*E$2:E$5)
What would be the most elegant solution? I need the option to change the percentage.

QUESTION
I'm gonna re-ask a question (Excel: SUMPRODUCT with percentages) that didn't get solved in another way:
I'm trying to calculate the workload/hours for each employee for certain projects. In column B you can see the responsible (100% of the workload), in C you can see which employee is taking 50% of the workload off the responsible employee. So I need the sum of all hours, while deducing of adding the 50% in case the workload is shared and giving it to the employee helping.
My current formula:
=SUMPRODUCT(($B$2:$B$6=$A7)*($C$2:$D$6<>"")*(1-$C$1:$D$1)*E2:E6)
ANSWER
Answered 2022-Feb-14 at 13:46QUESTION
I use the following formula to calculate the SUMPRODUCT of the values in a column with the condition that there is a match between B2:B6 and A1:A3 (shoutout to user:8162520).
=SUMPRODUCT(($B$1:$B$6=$A$9)*(G2:G6))
Now however I would like to subtract to that result the percentage in C1 and/or D1, and "give it" to one of the other blue numbers, again with the condition that there is a match between C2:C6 or D2:D6 and A7:A9.
So for example in G7 the result for "1" should be 50% of 10 + 75% of 5, because "2" takes 50% of 10(G2) and "3" takes 25% of 5(G5).
The point is to create an overview of how many hours employees (1,2,3) have to spend spend on project B2:B6 for each week (E,F,G), and what happens if other employees take a certain percentage of the workload (C,D). What is the most efficient way to do this?
The numbers in A, B,C, D are reference numbers, they should not be part of the calculation. Maybe it's clearer if I use letters. See also the right results for E7:G7. The outcome must be the sum of the values in each column (workload) minus the percentage in C and D IF there is someone sharing the workload:
...ANSWER
Answered 2022-Feb-11 at 17:35So deducting the percentage in C1:D1, presumably where there is no workload the result should be zero?
