Proper use of ALLSELECTED?

[macfuller]

I have the following measure which is returning 100% for every row.

Voucher Spend as Pct of GL:=
[Voucher Amt] / CALCULATE ( [Voucher Amt], ALLSELECTED ( Vouchers[Account] ) )

Voucher Amt:=SUM(Vouchers[Voucher Amount])

What I would like is for when I select certain accounts that the measure return what % of the visible total is showing.

At the top level I have an 'Account Tree' lookup table with an 'Account' column all the organization's GL accounts. A column in this table, NODE 7, identifies the GL accounts for Medical Supplies, Dietary Supplies, and so on. I have a slicer selecting "Medical Supplies" to give me the preferred list of GL accounts.

In between I have the 'Purchase Order' table. Each line of a PO has a GL Account, to which the 'Account Tree' links the Account field.

Then comes the Voucher table linked many:1 with the PO table. The Voucher table also has an Account field and the 'Voucher Amount' field with the spend on the PO item.

So when I select the "Medical Supplies" NODE 7 category in the slicer I want to list all the Medical Supply GL Accounts, their Voucher Amt, and the % of the overall Voucher spend on Medical Supply accounts. So I would like to get:

Account	Voucher Amt	Voucher Spend as Pct
Antiseptics	$1,500	37.5%
Catheters	$1,000	25%
Oxygen	$1,500	37.5%
Total	$4,000	100%

I have tried changing the ALLSELECTED ( ) portion of the CALCULATE statement to do the 'Account Tree'[Account], 'Purchase Orders'[Account], and 'Voucher'[Account] but in all cases each row returns 100% so I'm obviously not understanding the correct use.

Thanks for your help.

Sorry, I figured this out once I understood the source my confusion. My pivot table was displaying rows based on the GL Account description, not on the 4-digit account code itself that I was filtering on. Once I changed ALLSELECTED ( 'Account Tree'[Description]) the pivot table behaves as expected.

I constantly struggle, even if no one else does, with thinking that because I have filtered certain rows of the data via a slicer then filters within a measure will recognize any rows that are filtered rather than those that are specifically named, even if from the same table. There may be a DAX expression to recognize filters like that, just not ALLSELECTED...
