Data quality reporting using Generate Rows tool ideas

[gurth]

I'm pulling my Alteryx boots back on after a while now, so bear with me!😀

I'm checking data quality for a data set, an example of which is below..

Client_id	Name	Address	Phone
1	Adam	123 Sesame St	9123 4567
2	Becky	[Null]	[Null]
3	[Null]	3 Rosedale Cct	9456 7890

My desired output is this

Client_id	Name	Address	Phone	DQ_Issue
1	Adam	123 Sesame St	9123 4567	No issue
2	Becky	[Null]	[Null]	Missing address
2	Becky	[Null]	[Null]	Missing Phone
3	[Null]	3 Rosedale Cct	9456 7890	Missing name

...but using the Generate Rows seems to work iteratively between 2 existing values (usually numeric or date types). AM I barking up the wrong tree here?

The other thing I thought of would be pass each and every record through a formula tool that tests each individual DQ_Issue, then union and deduplicate, but for a million records, it might get expensive.

I think we can try something like this.
