In desperate need of a formula for a -basically- simple task
Here is the tweaked formula...
=INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),IF(MOD(COUNTIF(F$3:F3,F3),COUNTA(INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),)))=0,COUNTA(INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),)),MOD(COUNTIF(F$3:F3,F3),COUNTA(INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),)))))
Please try this and see if this is what you were trying to achieve...
In H3
=INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),COUNTIF(F$3:F3,F3))
Subodh_Tiwari_sktneer It sounded too good to be true... It works perfectly for the first part, but two things are not working yet:
- after the 3 accessory options are tested, the fourth test should use accessory 1 again, the fifth test should use accessory 3 again, et cetera. So, a continuous loop.
- products that have only 2 test accessories should cycle through those 2 (1-2-1-2-1-2 instead of 1-2-0-1-2-0)
Think you can figure that out? That would be amazing 🙂
If you tweak your master data to fill the empty cells for any product, if any, manually, the following Array Formula will return the desired output.
e.g. Cell D5 in your master data is empty which you can fill manually with the first occurrence of the accessory which is 'a' in this case. I have filled it manually in the master data.
See if you can tweak the master data manually for those empty cells if any. If yes, you can try the following Array Formula which requires confirmation with Ctrl+Shift+Enter instead Enter alone...
In H3
=IFERROR(INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),COUNTIF(F$3:F3,F3)),INDEX(H$2:H2,SMALL(IF(F$2:F2=[@product],ROW(F$2:F2)-ROW($F$2)+1),IF(MOD(COUNTIF(F$2:F2,[@product]),COUNTA(INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),)))=0,1,MOD(COUNTIF(F$2:F2,[@product]),COUNTA(INDEX(Table1[[accessory 1]:[accessory 3]],MATCH([@product],Table1[product],0),)))+1))))Then confirm with Ctrl+Shift+Enter instead of Enter alone.
If you have access to the dynamic array formula, you don't need the special key stroke Ctrl+Shift+Enter to confirm an array formula, Enter is enough in that case.
We're almost there! The only thing is: with this formula product 3 would be tested with accessories a-d-a-a-d-a-a-d-a-a-d-a, whil it should be a-d-a-d-a-d-a-d. This way I would test twice as much with 'a' as with 'd'. That would corrupt the outcome...
Subodh_Tiwari_sktneer This seems to be working 🙂 I still have to translate it to the actual file but if this works, you are truly a life saver! Thank you so much!
