Creation of PM or CM WO by external source

[Former Member]

I believe my request is pretty much standard, however I didn't find any info in existing threads.

If I need to initiate a WO execution based on an external source (for example, a message from Plant automation system) - what is the way to do it?

In my understanding, there must be a standard feature for SAP PM to "listen" to, say OPC server, and act upon certain condition.

Thank you in advance for help.

Hi.

Generally in SAP PM interface or automation with external source like measuring parameters such as temperature, pressure, vibration reading can be transferred to SAP system. Resulting the generation of notification if the value is out of the range. This come in the User exit IMRC0001 . It helps to trigger or generate a notification by system automatically. From this notification you can convert to Work order.

Thanks!

The way you described, notification and Corrective WO will be raised. Am I right?

In what form this external signal is transferred to SAP PM? Is it a OPC interface, or something else.

RenatF,

Unfortunately SAP cant "Listen" to external systems,Unless its visible inside. However as indicated above if the external systems can communicate the data(Either the exception or all the data records for a Particular Business scenario), then it can react based on the data and we could have SAP generate Transactional / ,Master data objects accordingly.

There are [different ways a communication|http://help.sap.com/erp2005_ehp_04/helpdata/EN/18/da766aaf5311d6b29f00508b6b8b11/frameset.htm] can be established between a external system and SAP. The choice of the pattern depends on the what the external system can do and what are the standards maintained or are required to be maintained. Some examples of communication technologies are

1) RFC (Remote Function call)

2) IDOC (Intermediate Document) / ALE (Application Link Enabling)

3) BAPI(Business Application Programming Interface)

4) Through a Middle ware (SAP XI , MQ series, Business connector,.Net Connector etc)

5) SOAP Framework

6) Web services

There are standard content available in all of them.

So if you could specify what you are trying to accomplish and what is available at your end, we would be able to suggest possible options

Narasinmhan,

Thanks for the info. From here, I will try to read a bit more about the options and then see what can be used in our case. At this moment in time, I am not ready to conclude the best option.

Renat.
