Hi Dee,
Missing Account Analysis looks for missing accounts based on your report definitions. If you have a report definition set to company TWO that contains a row definition named Income Statement, then company TWO will be checked for missing accounts for this report. If you attach a reporting tree to this report containing companies THREE and FOUR, then all companies will be checked for this row definition.
Missing Account Analysis is flexible and will check any row definition and reporting tree that are assigned to a report definition. If you have unassigned building blocks then they will not be analyzed. The key to handling multiple companies is that you have the row definition assigned to an individual report definition or are using that row definition with a reporting tree that lists each of your company in it.
If you are seeing missing accounts listed for a row definition, then that row definition is used for another company in this report, or another one.
