MDM Adapter doubt

[Former Member]

Hi

what are all the advantages of using MDM adpater in PI 7.1

1.Will MDM adapter accesses directly the repository (in console or data manager or syndicator)?

2.How MDM adapter can be compared with import manager or syndicator .

3. MDM adpater enables to load the data directly to any repository ?

4. how the integration of PI7.1 with MDM 7.1 takes place ?

am bit confused, can you pls explain ?

thanks

Hi Manian,

Please go through this link...

A small but quite interesting and useful presentation on SAP MDM 7.1 PI Adapter.

https://www.sdn.sap.com/irj/sdn/nw-mdm71?rid=/library/uuid/604b3c0c-5b6c-2b10-cc83-a7af75c70eaf

1.Will MDM adapter accesses directly the repository (in console or data manager or syndicator)?

Ans: MDM Adapter doesn't access the MDM repository; it access the port on which you want to drop the file or from which you want to pick the file. Now using MDM PI adapter you don't need to configure FTP for interacting with MDM repository's ready folder.

2.How MDM adapter can be compared with import manager or syndicator .

Ans: We can't compare MDM PI adapter with Import manager or syndicator. It is an adapter used to send/recieve data to/from MDM. After sending data to the inbound port ready folder; MDIS will import it to the repository. Similarly MDSS will syndicate the data and drop a file on outbound port ready folder and then MDM PI Adapter will pick the file.

3. MDM adpater enables to load the data directly to any repository ?

Ans: MDM Adapter doesn't loads the data into repository; however it just places the file in inbound port ready folder and then it is the job of MDIS to pick the file from there and import it into the repository. Using MDM adapter we can monitor complete end-to end process and we can also check that whether data has been successfully imported into repository or not.

4. how the integration of PI7.1 with MDM 7.1 takes place?

Ans: For this you will have to go through the link which I have provided in the beginning. It will give you some idea about it.

Hi Manian,

Please go through this link; it will give you a good idea about the new features of MDM 7.1

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0d0b0e7-f144-2b10-17a2-982103c9...

Some key points on MDM-PI Adapter; this will definitely answer all your questions:

1. MDM 7.1 will offer new functionality to directly push/pull data into/from MDM using the MDM JAVA API.

2. The MDM PI Adapter will support SAP Netweaver PI 7.0 and 7.1

3. The MDM PI adapter is shipped as a separate file to be deployed on the PI adapter engine.

4. Message flow between PI and MDM can be monitored end to end (e.g. show if messages have been recieved and properly imported into MDM)

5. Error handling is improved because the Communication Channel in PI is pointing to one specific Repository Port.

6. Restarting of messages if a service is unavailable is possible.

7. Configuration/System landscape setup/Integration

(a) MDM Adapter can be used instead of the File Adapter.

(b) Configuration of FTP is no longer needed.

(c) MDM Adapter is easy to implement and straight forward to monitor.

(d) Higher reliability of data transfer.

8. Message Flow PI to MDM

(a) Data sent from any connected system to PI is stored within PI's internal database.

(b) XML message is forwarded to the defined communication channel (MDM PI Adapter).

(c) MDM JCA Adapter itself invokes the MDM JAVA API sends the message to MDM using MDIS Port Functions.

(d) Store the message in XMl format in XML format into the corresponding MDIS port folder so that MDIS can import the files independently.

(e) "Finished import event" is thrown by MDIS and caught by the MDM JCA Adapter.

(f) The import status is used to update the PI monitoring accordingly.

9. Message flow from MDM to PI

(a) The Syndication event is triggered by MDSS as soon as the syndication is finished.

(b) The data is available as XML file in the corresponding port folder.

(c) The MDM JCA Adapter catches the syndication event and uses the MDSS Port functions to retrieve the data.

(d) PI XMl message is created and sent to the PI AF for reciever determination and further message processing.

(e) It is important to understand that only MDSS is able to throw the syndication event.

(f) A manual syndication using the syndicator does not throw this event, meaning that the MDM 7.1 PI adapter is unable to pick the XMl message coming from manual syndication.

All these points should give you a very clear picture of all the abilities of MDM-PI Adapter.

Hope this will answer most of your questions.
