transaction matching

hey everyone!

 

i have a follow up to my last post in regards to transactions. this time my data set problem is focused on trying to match the credit adjustments that correspond to a specific traveller's purchases. the credit adjustments were due to errors in transactions for which travellers got refunded.

 

im currently only able to match a portion of them because i cant find a suitable formula that will parse through each record, read the employee id, and keep that traveller's previous transactions in context when trying to match the corresponding credit adjustment.

 

the link to my data set is here: https://drive.google.com/file/d/1Q8e1l34jx8MifjuLP73Z8xjasFg5Pgo1/view?usp=sharing

 

so far i created 3 additional columns in power bi:

 

credit adjustment column =

CALCULATE(MAXX(Sheet1,Sheet1[amount]), Sheet1[Employee ID] = EARLIER(Sheet1[Employee ID]), FILTER(Sheet1, Sheet1[transaction type] = "credit adjustment"))
 
purchase column = IF(Sheet1[transaction type] = "purchase", Sheet1[amount],0)
 
credit matched with purchase = IF(Sheet1[credit adjustment column] *-1 = Sheet1[purchase column] && ISNUMBER(Sheet1[credit adjustment column]), "matched", "nope")
 
this is what i have so far however due to the limitations of the credit adjustment column formula, its only taking into consideration the MAX for each traveller but i would like it to keep into consideration every transaction for a given traveller when performing the calculation.
 
 
my expected output is that Jim halpert has one matched purchase/credit adjustment for -125/125, Margaret Carter has one matched for -1250/1250, Michael J Fox has one for -350/350, and Robert LeRoy Parker has one for -13/13
 
 
any tips to move forward greatly appreciated!

    Hi Phil-osophy ,

     

    To create two calculated columns as below.

    Column = 
- IF ( Sheet1[transaction type] = "credit adjustment", [amount], BLANK () )

    Column 2 = 
VAR a =
    CALCULATETABLE (
        VALUES ( Sheet1[Column] ),
        FILTER ( ALL ( Sheet1 ), Sheet1[Employee ID] = EARLIER ( Sheet1[Employee ID] ) ),
        Sheet1[Column]
    )
RETURN
    IF ( [amount] IN a, "matched", "nope" )
