SAP will apply this upgrade from February through March 2018 (see above).
Visibility Filters → Permission Filters
To reflect the fact that visibility filters can now also be used to control write access, the term permission filter replaces visibility filter in the IBP applications and in the documentation as of 1802. Particularly, the Visibility Filters app has been renamed to Manage Permission Filters. Also see the "Permission Filters" section in the What’s New in 1802.
Activation of Planning Area
Generally, you do not need to reactivate your planning areas when you upgrade. However, you may have to reactivate to take advantage of certain capabilities. Please review What’s New in 1802 for more information (available as of RTH, planned for Feb 6).
For additional activation guidance, please review the model configuration guide (available as of RTH, planned for Feb 6). If activation ends with an error you cannot solve, please create a customer incident.
The upgrade generally does not require that you install the new version of the IBP Excel add-in. You can decide to install the new version at any time, for example, when you wish to use the new features that are available with the new add-in version. For more information, see What’s New in 1802 (available as of RTH, planned for Feb 6).
Customers can download and install the latest Excel add-in version on the SAP Support Portal. For more information about restrictions related to the IBP Excel add-in, please check SAP Note 2519069.
