Best approach for Date sequence check

[TrentS]

Good day to all,

I have about 20 events/dates in a shipping sequence that I need to run a check on.
I need to determine two things:

1. Any missing dates in the sequence (think missing scans during the process)

2. If any dates are out of sequence.

Using the screenshot above.
1. I would need a count of the two rows missing dates. (Lets just call it per row at this stage, so 2 in this case.)
2. In order 105 (yellow) obviously we cannot pack it after shipping so I need to capture that.

Ultimately I would like to produce those rows in an output visual table as well as a count.

I have a secondary table that ranks the sequence to use as a reference. (Static/Imported)
Given the high number of events, nested IFs and Switch do not seem to be elegant solutions as I have seen in my search of this forum.

Suggestions on how to approach this?
I appreciate your time!

Thank you Ashish and Ryan. Kudos given.
I am going to leave it as unresolved for a bit as I worry about upscaling that to the 20+ dates that would have to be used in those measures/columns. This data set already has a considerable number of custom columns added and I worry about adding even more.
Any thoughts on an approach to that many steps needing the comparisons? (I only placed 4 in the example but there are considerably more in the actual data set.)

Hi,

Write these calculated column formulas

Missing dates = 1*(Data[Order placed]=BLANK()||Data[order processed]=BLANK()||Data[packed]=BLANK()||Data[shipped]=BLANK())

Dates ordered properly = 1*(if(Data[Missing dates]=1,BLANK(),not(Data[order processed]>=Data[Order placed]&&Data[packed]>=Data[order processed]&&Data[shipped]>=Data[packed])))

Hope this helps.

@TrentS 

you can create two measures

Measure = CALCULATE(COUNTROWS('Table'),FILTER('Table', ISBLANK('Table'[order processed])||ISBLANK('Table'[packed])))

Measure 2 = CALCULATE(COUNTROWS('Table'),FILTER('Table', 'Table'[packed]>'Table'[shipping]))

or create columns

missingdate = if(ISBLANK('Table'[order processed])||ISBLANK('Table'[packed]),1,0)

wrongdate = if('Table'[packed]>'Table'[shipping],1,0)

then you sum the column to get the total number
