Print Commercial Documents Report customization is not working

We have a requirement to add a single column in the report.

We followed the steps of customizing seeded report. After opening the data model (Print Commercial Documents) and saving it without any changes, the report is getting error out. We have not added any column yet but it is giving error "SQL command not properly ended"
