Is it possible to create an array formula based on a table where it searches for distinct combinations of data before summing? Here is some sample data:
| A | B | C | D |
---------------------------------------------------
1 | 1 Jun | Charlie | D | 1.3 |
2 | 1 Jun | Charlie | N | 1.4 |
3 | 1 Jun | Dave | D | 1.3 |
4 | 2 Jun | Charlie | N | 0.6 |
5 | 2 Jun | Dave | D | 1.5 |
What I'd like the array formula to be able to do is look at the table, ignore column B and tell me which distinct rows (A, C and D or more criteria) and sum column D if they are unique. In this example, it should not sum Row 3 because on 1 Jun, "D" already has a 1.3.
PivotTables and VBA are out as I am designing this for the lowest level user on super restrictive computers.
EDIT: Picture of expected results, changed sample data to reflect results.
Kind of the data I am looking for.... I replaced the ID with the LName to visualize. I need to exclude individuals and get only aircraft hours by their modes. You can see toward the bottom of the image, 2 people are on one aircraft. I used MAX to keep it from SUMming it up and skewing the hours.
The levels on the left are by Date, Aircraft, Flight Number, then Person. I need to aggregate the hours down to the Flight Number of each date.
The original formula is
=SUM((FLTD_HRS)*(FLTD_DATE>=$D$3)*(FLTD_DATE<=$D$4)*(IF(FLTD_ACFT_MDS=CONFIG!$F$8,1,0)))
however, as it is, does not get me unique flights. I'd prefer an array formula to a PivotTable.... XD
You can add a new column (E) to your first table and then lookup the value in the new table or calculate in the new table.
E = SUMIFS(D$3:D$30,A$3:A$30,A3,C$3:C$30,C3,D$3:D$30,D3) E1 = {=INDEX(A$3:E$30,MATCH(G3&H3&I3,A$3:A$30&C$3:C$30&D$3:D$30,0),5)} E2 = SUMIFS(D$3:D$30,A$3:A$30,G3,C$3:C$30,H3,D$3:D$30,I3)
I ended up creating a calculation sheet to create a unique key for each flight by concatenating the fields I wanted to match and also eliminated the duplicates by searching for "VALID_PC" which searched for the highest rank of the person in the crew flying. The formulas I used in columns K and L were:
=IF(IFERROR(MATCH(H3,VALID_PC,0),"0"),A3&RIGHT(C3,5)&D3&E3,0)
and
=IFERROR(IF(A2=0,0,IF(COUNTIF($K$2:K3,K3)>1,0,1)),0)
This allowed me to do a simple {=SUM} on whether column L had a 1 in it on the main page..
I do appreciate the help and effort you all put in to help me.
