DV TEXTAGG excludes column from the result if it is blank

Issue

• TEXTAGG function excludes the column from the result if it is blank

TEXTAGG(FOR Last_Name,First_Name,Middle_initial,Currency_Code DELIMITER '|' QUOTE '"')

In the above example,if middle name is blank, then it should still show one empty column with "|" delimiter as shown below:

Smith|John||USD

But it returns output excluding middle name since it is blank:

Smith|John|USD
