How to get Count number of prints Invoice report

Hi Team,

I would like to display the print count in the 'SO643000' ‘

Invoice & Memo’ report. Please find the attached report.

I referred to the mentioned blog for a solution,

https://asiablog.acumatica.com/2019/02/how-to-count-number-of-prints-in-acumatica.html

but it is not working. I also added a subreport for this, but I am not getting the desired results. My goal is to show 'PRINT' the first time and second time is to show  'REPRINT' . However, the solution involving audit history always gives me incorrect results and sometimes results in a blank output.

Kindly assist me with this issue.

Regards,

Sagar
