Hi,

How do we differentiate between info,control and system parameters. Currently using EM with TM 9.1.

Hi Dipak,

There were enough discussions in this forum on this topic earlier.

Please check this link for detail information about this topic.

You can check this SAP OSS note 1260125 - Configuring search fields for the Web Interface

some main points:

1) system parameters are stored in index table Event Header extension table and should be used for web UI selection parameters

2) you can not update a system parameter via event message

3) control parameters can be updated via event messages: e.g. if freight orders are being tendered

then you probably have to change the carrier based on tendering results

4) control parameters are not stored in indexed table

And thus should not be used for selection on web UI

Thanks,

Deb

Hi Deb,

I have to correct you in your point 2): "you can not update a system parameter via event message". It is possible to update system parameters via event message. You can use either activity HDR_EXT_VALUE_UPDATE or PARAMETER_CHANGE_NEW.
