Is it possible to use both online and local version?
You may use both Online and Local PC application, but only one version can be used on one particular day.
So, if you make a substitutions for Monday in the online version, you can do substitution in local version on Tuesday and still publish it to the online version.
If you, for any reason, want to do the changes in local version on a day where you already have some changes created online, you will first need to delete the online changes for this version from the online version:
Important: If you do changes online, they can not be transferred to the local version. So if you are using both, or if you switch from local to online version in the middle of the year, then you have to do the reports and summary statistics in the online version.
