Synchronizing Data Using Data Carrier Synchronization 

Use

You must use data carrier synchronization to ensure that mobile clients can synchronize data with the DOE by using storage mediums, such as a floppy disk, CD, DVD, or USB drive. Based on your requirements, you can use the following options:

·        Download

Allows you to download the files to a storage medium. After you download the files to the required storage medium, you can send this storage medium to the required device. In this case, the files contain data that the device must receive from the DOE as part of the synchronization process.

·        Upload

Allows you to upload the files from a storage medium to the DOE and trigger synchronization. In this case, the files contain data that the DOE must receive from the mobile client as part of the synchronization process.

·        Upload and download

Allows you to:

¡        Upload the files from a storage medium to the DOE and trigger synchronization.

¡        Download the files to a storage medium. After you download the files to the required storage medium, you can send this storage medium to the required device.

If you want to synchronize data for a migrated application that uses two-way SyncBOs, for example MAM, then the device user must first store the data on the storage medium and send it to the administrator.  You must then perform the upload and download simultaneously by using the upload and download option.

Procedure

...

Log on to the SAP NetWeaver AS and start transaction SDOE_DISC_SYNC.

Uploading Files from the Storage Medium to the DOE

       1.      In the Disc Sync screen area, choose Upload.

       2.      In the Directory field, enter the path of the folder where the files are stored.

We recommend that you copy the files from the storage media to a folder in your local file system before you start to upload the files. This ensures that you can upload files quickly.

       3.      Choose Execute.

Downloading Files from the DOE to a Storage Medium

...

       1.      In the Disc Sync screen area, choose Download.

       2.      In the Directory field, enter the path of the folder where you want to store the files.

We recommend that you copy the files to a folder in your local file system instead of directly copying the files to the storage media. This is because you cannot directly write data on some storage media types such as a CD or DVD.

       3.      In the Media Size field, enter the type of storage media you want to use.

If you select the User Defined option as the media type, then you must also specify the size of that media.

       4.      To encrypt the data, choose Encrypt.

       5.      To sign the data digitally, choose Sign.

       6.      In the disc sync devices screen area, to specify the devices for which you want to download files, choose Add Devices For Download.

       7.      In the RMM Name field, enter MOBILE.

       8.      Choose Device List.

       9.      Select the required devices and choose Continue.

   10.      Choose Execute.

During the download of files to the storage medium, if new data is pushed to the outbound queues, then to get this new data, you must restart the transaction SDOE_DISC_SYNC.

Performing the Upload and Download of Files Simultaneously

...

       1.      In the Disc Sync screen area, choose Upload & Download.

       2.      In the Directory field, enter the path of the folder where the files are stored.

We recommend that you copy the files from the storage media to a folder in your local file system before you start to upload the files. This ensures that you can upload files quickly. After the upload is complete, the files that must be downloaded are downloaded to a new folder in the same location where the upload files were originally stored. This new folder is created only when the files are downloaded.

       3.      To encrypt the data, choose Encrypt.

       4.      To sign the data digitally, choose Sign.

       5.      Choose Execute.
