Hi experts

Someone could give some informations about MAM.

MAM is an aplication and must be instaled in a server and uses a midleware to replicate informations from and to R/3 ?

How users can access the system via Pocket ?

Thanks

Hi,

You have 3 layers here. One is actual backend R/3 system. MAM is a part of plant maintenance in R/3 system and comes as a part of standard. For running MAM application, some mobile specific customization needs to be done for every user as a part of implementation.

Now you have middleware system which can be Mobile Infrastructure 2.5(part of netweaver 2004 stack) or Mobile Infrastructure 7.0(part of Netweaver 2004s stack) or DOE(Netweaver Mobile 7.1). Using Bapi wrappers from the R/3 systems, some structures are created in these systems and later the data from the R/3 system is replicated to these systems.

Now coming to client side applications, Using the structures created in the middleware system, an application is developed and which will communicate using smart sync layer(capable of exchanging only delta data and not complete set). This application can be deployed on to a pocket pc and based on the configured user, some set of data is initially downloded from the middleware to the client. Using this data, now the user can create/update/delete the data on his pocket pc and synchronize the same to the R/3 system.

Hope this clears your question a bit. For more technical details its better to go through individual documentations.

Best Regards,

Hi,

xMAM is an application running on MI. MI is the Mobile Framework from SAP that runs on PDA. First of all you need to setup a MI infrastructure with Middleware SErver and install the MI runtie on PDA. This allows to send data from R/3 to PDA and from PDA to R/3. Once this is working, you need to install MAM application on top of MI framework. MAM takes the MI functions and sends the related data to the device and back. So MI is the transport layer, while xMAM is the business logic - in simple words - and you need both.

To get a better understanding read the MI documentation first - MAM is just an application on top as I said.

Hope that helps.
