Hi Dipak,

Preprocessing Functionality provides the custom validation check before posting the events to event handlers .

Example when posting the event from webui or idoc  you can enable the date validation or location validation .

Sample scenario :

if you are posting a event from location which is not maintained in location master  based on custom check you can respond to event sender or park the idoc in error status and reprocess it later using BD87.

even you can enable the custom table validation which is not supported in standard EM solution.

Preprocessing is carried out at the beginning of Event Message BAPI. You can change the Event Message, do customer specific checks etc.

It is used for various use cases.

Also check docu in SPRO.

Can you provide some examples to understand it better.Also for preprocessing to work is there any function module or just configuratiuon will activate this functionality.

Hi,

you can have a look at this blog: http://scn.sap.com/community/scm/event-management/blog/2007/12/04/scem--web-interface-check-event-me...

It is an (old) example how you can use the preprocessing functions. You need to create the function via customizing under Event Messages, Status Queries, and Web Interface -> Define Criteria for Event Message Processing. Here you find also more information in the help.

Best regards,

Hello Dipak,

check the TM-EM Integration guide:

http://help.sap.com/SCENARIOS_BUS2012/helpdata/EN/CC/EF6891DBCB4CF59ECC8BC77E680528/CG_TM_EM.pdf

and note 1527790.

There is an example that shows how you could use it. Only one use case for that you can use it but it shows what is possible.

Best regards,

Steffen
