Hi All...
I am trying to add a whole number that exists in its own column, via a calculated column, to a date in a related table based on project phases, with no success. If the phase is Execute, the New Start Date shouldn't change, if Plan, add the whole number to the Start Date and return a New Start Date. The expression always returns the same date, or a blank. Can anyone see where the flaw is?
Additional info; there are other project phases in the related table whose dates should remain the same.
Hi @bchager6
Try this
New Start Date =
IF(RELATED('RelatedTable'[Phase]) = "Execute",
IF(RELATED('RelatedTable'[Phase]) = "Plan",
DATEADD(RELATED('RelatedTable'[Start Date]),'CurrentTable'[Total Time Column],DAY),
RELATED('RelatedTable'[Start Date]))

@AlB Thank you. I tried that and Power BI returns an error: "The first argument to 'DATEADD' must specify a column."
The two tables I'm working with are related via a cross filter in both directions if that's relevant to the error.
You should stay away from bidirectional relationships unless there's a very good reason to use them and, more importantly, you know very well what you are doing. Try this and if it doesn't work please share a sample of your tables and provide an example to show the expected result based on that.
New Start Date =
IF(RELATED('RelatedTable'[Phase]) = "Execute",
IF(RELATED('RelatedTable'[Phase]) = "Plan",
RELATED('RelatedTable'[Start Date]) + 'CurrentTable'[Total Time Column],
RELATED('RelatedTable'[Start Date]))

@AlBI made one tweak and realized I overcomplicated the expression with a nested IF when I didn't need to, given the only dates that need to change are for those projects that are in the Plan phase. Placing the RELATED function at the end of the 3rd row in the expression helped also.
New Start Date =
IF(RELATED('RelatedTable'[Phase]) = "Plan",
RELATED('RelatedTable'[Start Date]),
'CurrentTable'[Total Time Column] + RELATED('RelatedTable'[Start Date])
)
