Table Calculation (IF THEN ELSE)

[Anonymous]

Hi Everyone, 

I have 2 tables joined together using Left Out Join.

Master Table
App ID	App Name	Department
1	App1	Department1
1	App1	Department2
2	App2	Department2
3	App3	Department3

Table 2
App ID	App Name	Department
1	App1	Department1
1	App1	Department3
2	App2	Department2
3	App3	Department3

I would like to check which App ID & App Name has a mismatch in terms of Department in form of a table. I used a custom formula to check that (IF MasterTable.Department = Table2Department, "MATCH",, "MISMATCH") and use Mismatch to filter out the results. But the results also contains the scenario where MasterTable.App1 has been flagged as mismatch because MAsterTable.App1.Department2 <> Table2.App1.Department1 (But since MasterTable.App1.Department1 is already matched with Table2.App1.Department1), how do I incorporate that exclusion in my formula? 

Thank you in advance

Hi @Anonymous ,

Please new two calculated column:

KEY = 'Table2'[App ID]&'Table2'[App Name]&'Table2'[Department]

Check = 
VAR _key = 'Master Table'[App ID] & 'Master Table'[App Name] & 'Master Table'[Department]
VAR _count = CALCULATE(COUNTROWS('Table2'),FILTER(ALL('Table2'),'Table2'[KEY]=_key))
VAR _result = IF(_count<>BLANK(),"MATCH","MISMATCH")
RETURN
_result

Hi,

in table 2,

Match/Mistmach column = IF( COUNTROWS(CALCULATETABLE(Master table,'Master table[NameDepartment] = EARLIER ( 'Table 2[NameDepartment]),'Master table[App] = EARLIER ( 'Table 2[App])))>0,"Match","Mismatch")
