Conditional column based on a subset of column value

Hi Experts, 

 

I cannot fully get row/query context when doing a calculation. I have got some data to illustrate and hoping to get some help, below is my data. I want created a conditional column to display "Order type" for "Transaction ID", so for each "Transaction ID", there are the conditions.

1. If "order type" F then  F for all "transaction item no" in that "transaction id"

2. If "order type" C then  C for all "transaction item no" in that "transaction id"

3. If transaction id have both C and F then "F" for all "transaction item no"

4. if order type is null for that transaction id e.g. transaction id 5 in below, then "F"

 

Transaction ID    Transaction Item No        Order type          Conditional Column 

1                         001                                   F                          F

1                         002                                   Null

1                         003                                   Null

2                         001                                   C                          C

2                         002                                   Null

3                         001                                   C                          C

3                         002                                   F                           F

4                         001                                   C

4                         002                                   C

5                         001                                   Null                       

5                         002                                   Null                       

Ideal result

Transaction ID    Transaction Item No        Order type          Conditional Column 

1                         001                                   F                          F

1                         002                                   Null                     F

1                         003                                   Null                     F

2                         001                                   C                         C

2                         002                                   Null                     C

3                         001                                   C                         F

3                         002                                   F                          F

4                         001                                   C                         C

4                         002                                   C                         C

5                         001                                   Null                     F

5                         002                                   Null                     F

 

Can't achieve this conditional column I want with conditional column as it only gives if then else and don't take calculate column context, which syntax do I need to use?

 

 

Thanks

replace "Undefined" to "F"

Conditional Column = 
var _orderF = calculate(countrows('Table'),allexcept('Table','Table'[Transaction ID]),'Table'[Order type]="F")
var _orderC = calculate(countrows('Table'),allexcept('Table','Table'[Transaction ID]),'Table'[Order type]="C")
return
if(_orderF > 0, "F", IF(_orderC > 0, "C", "F"))

Hi @Anonymous 

try a measure

Conditional Column = 
var _orderF = calculate(countrows('Table'),allexcept('Table','Table'[Transaction ID]),'Table'[Order type]="F")
var _orderC = calculate(countrows('Table'),allexcept('Table','Table'[Transaction ID]),'Table'[Order type]="C")
return
if(_orderF > 0, "F", IF(_orderC > 0, "C", "Undefined"))

Hi @az38 , that didn't work, as it counted transaction ID that does not have any values in them as well, so transaction ids that dont have "F" or "C" would be F as well.

Output =
var Check_C =
ISEMPTY(FILTER('New Text Document','New Text Document'[ORder Type]="C" && 'New Text Document'[Transaction ID]=EARLIER('New Text Document'[Transaction ID])))

var Check_F =
NOt(ISEMPTY(FILTER('New Text Document','New Text Document'[ORder Type]="F" && 'New Text Document'[Transaction ID]=EARLIER('New Text Document'[Transaction ID]))))
return
IF(OR(Check_C,Check_F)<>TRUE,"C","F")
