DAX to get value from other column if "text before delimiter column" is blank

[Kandidel]

Hi there,

 I have created a column in my model using "Insert Text before delimiter":

Table.AddColumn(#"Changed Type", "Text Before Delimiter", each Text.BeforeDelimiter(Text.From([Project ID], "en-GB"), "."), type text)

Partly the result is blank. In this case, I would like to have the value from column [opportunity code] in this table.

I have no idea how to get this working. Please help. Thanks in advance.

Hi Ibendlin, thanks for offering support. I have managed to go ahead with my issue by using a help colum where I check, if field in column "Masterproject" is empty and set respective neded value with help of a Switch-Function.
