Unable to convert lead after mass update. Error " The activity was imported, therefore you cannot u
I have a customer who says that several leads that had activities (completed tasks) were imported by mass-update and now leads are unconvertable due to that. When trying to convert lead, they are getting error " The activity was imported, therefore you cannot update. Error (SBL-DAT-56810)."
Is there any reason why we cannot convert after a mass update ?
