Measure Help!

Dear All

I am seeking your help to show “error” on all Invoices in PowerBi if Payment or Batch No is updated twice in the same Invoice number.

So basically “Per Invoice”  Payment & Batch No should be always updated once else it should show as an Invoice error.

Order Reference and Account Number can be shown multiple times per Invoice. Can I achieve this using a Measure?

Please click here to access the sample report.

Thank you in advance.
