Dividing rows

[will1296]

Hi,

Im new to power BI and am facing some problems here.

I have a table like this:

CAMP	TYPE	ITEM	UNITS
201701	A	Apple	100
201702	B	Lemon	50
201702	A	Apple	1000

I'd like to proportion breakdown the units to previous month, current month and next month, so that I have a dynamic table that looks like this:

CAMP	ITEM	UNITS	REMARK
201612	Apple	30	M1
201701	Apple	50	M2
201702	Apple	20	N2
201702	Lemon	45	N1
201703	Lemon	5	N2
201701	Apple	300	M1
201702	Apple	500	M2
201703	Apple	200	N2

So, the each CAMP column is breakdown into previous month, current month and next month and the units are breakdown as below table. If the TYPE column is A, then breakdown the units with matrix [0.3,0.5,0.2], and remark M1, M2, N1 or N2 corresponding to the the table. The breakdown index is as below table:

A		B
30%	M1	90%	N1
50%	M2	10%	N2
20%	N2

I've been trying to write a DAX formula to convert this, but it doesnt work, and I've been stuck on this for days. Can anyone point me in the right direction as to DAX to split out units into the second table?   

Thanks in advance.

Hi @will1296,

For BreakDown table, I changed its structure to make it more usable.

In CAMP table, I added some auxilliary columns as highlighted in below image.

Then, I make PreviousMonth, CurrentMonth and NextMonth records to be listed in a single column via UNION. And use LOOKUPVALUE function to refer to BreakDown value in BreakDown table.

For more detailed steps, please see the attached .pbix file. CAMP Table_2 is the result table.

Best regards,

Please post the correct table structure of the breakdown index table. Show us column headers and detailed records.
