Count based on multiple columns from different tables

Hi PBI Community,

 

I am working on an interesting problem. I have two tables A and B. 

Table A: Contains a list of transactions with a transaction number, item, date and status.

Table B: Contains the list of items that is unique.

Table B has a 1 to many relationship with table A.

 

Objective: Count the number of elements in Table A based on values in other columns within and display as a calculated column in table B.

 

Criteria: 

For the highest Transaction number for each item in table A:

If the due date is after 5 January AND if status is A or B

Count +1 for corresponding item in table B.

 

Data and expected result:

TABLE A
Transaction NumberItemDue DateStatus
1Item123-JanA
2Item125-FebB
3Item110-JanC
1Item211-JanA
1Item311-JanA
2Item311-JanC
4Item313-JanB
4Item302-JanA
1Item401-JanC
1Item115-JanA
1Item416-JanB
1Item517-JanB
1Item517-JanA

 

TABLE B
ItemResult
Item10
Item21
Item31
Item41
Item52

 

Eg1. Item 1 has 4 transactions, the highest Transaction number is 3 with a due date of 10 Jan and Status C, so result is 0 in Table B.

Eg2. Item 2 has 1 transaction, with a due date of 11 January with a status A so result in Table B is 1.

Eg3. Item 5 has 2 transactions of the same number with the same due date but different statuses A and B so result in table B is 2.

 

Where I've gotten to: I've managed to flag the max transaction number for each item in table A.

 

Max Transaction = CALCULATE(MAX(Table A[Transaction Number]),ALLEXCEPT(Table A,Table A[Item]))

 

Any one have any ideas on how to obtain the column Result in table B based on these criteria? 

 

Thanks,

Dilip

Why not do it in Power Query?
