Lookup with switch case

Table 1: consisting of Jobs:
pbi_community_job.png

 

Table 2:  Invoices of certain jobs in the job table. Not all the jobs have an invoice.

How do I calculate the Status column in the Job table using DAX?

 

Logic for status:

  • If flag=1 for job id in invoice, then Status="Current"
  • If flag=0 for job id in invoice, then Status="Old"
  • If job id in jobs is not there in Invoice, the "NG"

Excel for reference: Sample

 

Thanks!

Status =
VAR _Flag =
    CALCULATE (
        MAX(Invoices[Flag]),
        FILTER(ALL(Invoices[Job ID]),Invoices[Job ID] = Jobs[Job ID])
    )
RETURN
    SWITCH (
        _Flag,
        BLANK (), "NG",
        0, "Old",
        1, "Current"
    )

Hi @Anonymous

 

Try this for your Status column in Jobs:

 

Status =
VAR _Flag =
    LOOKUPVALUE (
        Invoices[Flag],
        Invoices[Job ID], Jobs[Job ID]
    )
RETURN
    SWITCH (
        _Flag,
        BLANK (), "NG",
        0, "Old",
        1, "Current"
    )

Hi @AlB,

 

I was not aware about the Return function, Thanks!

 

One small issue, the job ids in the invoice table aren't unique. Hence while looking up, i get the error: "A table of multiple values was supplied where a single value was expected."

 

 

Based on the resolution Here, I tried doing it like:

VAR _Flag = CALCULATE (
    FIRSTNONBLANK ( Invoice[Flag], 1 ),
    FILTER ( ALL ( Invoice ), Invoice[Job ID] = Job[Job Id] )
)
   

But some rows are getting misclassified here.

 

Any other way to handle this?

 

Thanks

Well, first we'll need to clarify what you want to do when there are several different flags for a Job ID. Which one do you want to select in that case? That should have been stated in the opening question.

Yeah should've mentioned earlier, sorry about that.

There is a 1:* relation between job and invoice tables i.e. one job can have multiple invoices but not the other way around. 

 

  • If even a single occurrence of a job id in Invoice table has flag = 1, then respective job id in job table should have Status="Current".
  • If all the occurrences of a  job id in Invoice table has flag = 0, then respective job id in job table should have Status="Old".
  • If job id in jobs is not there in Invoice, the "NG"

That's it

        BLANK (), "NG",
        0, "Old",
        1, "Current"
    )
