NESTED IF

[Anonymous]

Hello, I am stuck with a nested if condition problem. The Result table is what I am trying to create in powerbi. Can anyone help me out with this, thanks in advance.

LOGIC:

1)IF [CODE] = "M" && [OPDSC] = 2SH,2LG THEN [RESULT] = "M"

2)IF [CODE] = "M" && [OPDSC] <> 2SH,2LG THEN CHECK CURRENT ROW [OPDSC] WITH PREVIOUS ROW [OPDSC] IF IT IS SAME THEN  [RESULT] = "M/A/B"

3)IF [CODE] = "M" && [OPDSC] <> 2SH,2LG THEN CHECK CURRENT ROW [OPDSC] WITH PREVIOUS ROW [OPDSC] IF IT IS NOT SAME THEN  [RESULT] = "A/B"

4)IF [CODE] <> M THEN [RESULT] = USE CORRESPONDING ROWS[CODE]

@Anonymous , try this calculated column:

DAX Column = 
VAR Current_Index = TableName[Index]
VAR Prev_Index = Current_Index - 1
VAR Prev_OPDSC = 
	CALCULATE(
		MIN(TableName[OPDSC])
		,ALL(TableName)
		,TableName[INDEX] = Prev_Index
	)
VAR Result = 
	SWITCH( TRUE()
		,TableName[CODE] = "M" 
			&& TableName[OPDSC] = "2SH,2LG"
				, "M"
		,TableName[CODE] = "M" 
			&& TableName[OPDSC] <> "2SH,2LG"
			&& TableName[OPDSC] = Prev_OPDSC
				, "M/A/B"
		,TableName[CODE] = "M" 
			&& TableName[OPDSC] <> "2SH,2LG"
			&& TableName[OPDSC] <> Prev_OPDSC
				, "A/B"
		,TableName[CODE] <> "M"
				,TableName[CODE]
	)
RETURN
Result

This code first determines what the previous index is, and gets the [OPDSC] for that row.

The SWITCH() TRUE() pattern lets you evaluate multiple statements, and returns the first result that is true.

Just make sure to replace all instances of "TableName" with the name of your table!

Thank you soo much, Chris, it worked perfectly. Now I understand the switch statement better.👍
