Be.Smart T4I -> Be.Smart T4I -> Advanced settings -> Auto iProperties -> Validate Document On Save
On invoking the Save command, a check can be performed whether the document being saved conforms to preset rules. The activation of the individual validation checks can be set in Advanced settings.
If at least one of the validation checks fails, the save process is terminated, and the issue description is listed in a dialog box.
The assembly must not contain virtual components. If they are present, the save command is canceled.
If there is a problem with units in BOM, the assembly cannot be saved.
The iProperty Part number must not start or end with spaces, otherwise, the document cannot be saved. This rule applies not only to assemblies but also to parts.
