I am researching the use of SAP MAM on a system that can be off line for long periods of time. I understand some of it's basic uses...
- Transfer Work Order information from back end system to the mobile device
- On the mobile device...
- View historical data
- Confirm task completion
- Record Time & Materials
- Create notifications
- Assign Tasks, etc.
Once Synced with SAP, task confirmations and Material confirmations update Billing and Inventory.
My question is this...
How much functionality does MAM have while disconnected? For example, can maintenance planning run and create service orders on the mobile device while disconnected (assuming measurement documents are created on the mobile device)?
Thanks in advance for your assistance.
Hi John,
You can at MAM as a tool that allows a user ,while disconnected from the backend, to perform a limited set of PM/CS functions, like create/change order/notification, material/time confirmations, etc.
To be able to do anything, mobile user needs to perform synchronisation (via SAP Mobile Infrastructure as a middleware) to get all necessary information downloaded to the local database of his device. Then activities (that you listed in the beginning can be performed).
Until device is synchronised again with the backend any changes are local to the device and unknown to the R/3 system.Synchronisation is always triggered by the mobile device and if it is successful order/notifs, etc. are updated or created in R/3 system.
To answer you last question: maintenance plan can run in R/3 anytime (it obviously does not run on the device), then order MUST be assigned to a mobile user, then AFTER mobile device triggers synchronisation, those orders that are assigned to that specific user will be downloaded to the mobile device.
Once order is downloaded, mobile user can do changes to that order (like uesr statuses, operations, material/time confirmations, ect.).
In MAM database structure, though, meas. documents are not related to orders directly.
The way it works: when order is downloaded to teh device it brings equipment/func.loc associated with this order (either on header level or tech.objects list). Equipment/Func.loc in turn triggers meas. points associated with this technical object to be downloaded to then. Now! user can create meas. docs for the meas. points.
After device sync, any changes user has done since last sync will be uploaded to the R/3 system.
Hope that helps,

Thanks Larissa. That's what I suspected but wanted confirmation.
