Cannot resolve the table name: [PX.Objects.CR.CRLeadContactValidationProcess+Contact2]

When it comes to this kind of errors, if possible, user could test by reverting report back to the out of box report, which would also resolve the issue, this would make use of the default report 

Hello everyone,

This usually happens when out-of-the-box report was customized before the upgrade: the upgrade procedure only changes uncustomized out-of-the-box reports to preserve changes, and the custom reports should be adjusted by the customizer.

There are plenty of examples in our KB, here is one of them:

Also, there are techniques collected on how to review and include changes between major versions in your customized reports:

We are woking on providing better tools to resolve such issues.

Hi Chris,

Do you have a customized version of the stub?  If yes, you could try the original version of the stub.  I would also recommend you contact your business partner as they can open a support case with Acumatica. 

If you want to see version of the form, you will need to have the ReportDesigner role.  Then expose the from to the payroll desk top by opening the site map, search for PR..64.10.15.  In the Workspaces column select Payroll, the Category column select Reports and save.  This places the from in the Reports section of the payroll desktop.  This will allows you to open the from control and you can view the REPORT VERSIONS tab.
