Object documentationParameters

 

Parameters are variables of objects and processes that are relevant to supply chain event management (SCEM-relevant). The parameters contain the information from the application system about an application object. They are defined and stored in SAP Event Management in the form of control, info, and system parameters. This means that you can use SAP Event Management independently of an application system.

In addition, you can also set values for rule processing parameters while processing a rule set. You can use these rule processing parameters to transfer values from one task to the next task in the rule.

 

Control, Info, and System Parameters

You use control, info, and system parameters in SAP Event Management in the rule set for processing search or information queries.

To select the control and info parameters in SAP Event Management Customizing, you create a parameter list for control and info parameters in the application system.

SAP Event Management stores information from the application system in the following parameter types:

  • Control parameters

    You use control parameters, together with system parameters, to specify the event handler type and the characteristics for an event handler.

  • Info parameters

    You use info parameters for all additional information that you want to transfer to the event handlers in SAP Event Management for display purposes. If you have permitted the use of info parameters for condition processing, you can use them for processing in the rule set. To do this, set the corresponding indicator within an info parameter.

  • System parameters

    These are all the control parameters that the application system transfers to the corresponding fields in the event handler extension table, for example, the service provider ID or the destination ID.

You need the parameters for the following:

  • Control parameters to define and to check the process steps in SAP Event Management, for example, the service provider name, document type, or material type.

  • Info parameters for information and query purposes, for example, location.

  • System parameters to specify the field values for typical search queries to SAP Event Management.

    System parameters are therefore a special type of control parameter from the application system that use database indexing to enable you to make quicker search queries.

    Example Example

    For a transportation process, you define the country of origin and the destination country, the name of the carrier, the mode, and the departure date as system parameters.

    End of the example.

  • Control and info parameters to make your queries about SCEM-relevant information to SAP Event Management and to transfer the SCEM-relevant information to a data warehouse system.

Rule Processing Parameters

In SAP Event Management, you use rule processing parameters to transfer values from one task to another task in a rule. You use an activity to set the value of a rule processing parameter. You can access this value using an activity within a rule or using a rule condition.

You have both read and write access to rule processing parameters during rule set processing.

Specify Parameters in the Application System

Choose the transaction for defining SAP Event Management interface functions in the application system to specify a parameter list for control and info parameters. You get these parameters as a selection list when defining expected events and control parameters in Customizing for SAP Event Management. For more information, see Customizing for SAP Event Management in the application system under Start of the navigation path Event Management Interface Next navigation step Define Application Interface End of the navigation path.

Specify Parameters in SAP Event Management

In SAP Event Management, choose the transaction for defining control, info, and rule processing parameters and the transaction for defining system parameters.

For more information about defining parameters, see Customizing for SAP Event Management under Start of the navigation path Event Handlers and Event Handler Data Next navigation step Parameters End of the navigation path.

Structure

Info and Control Parameters

Info parameters consist of either text for information and query purposes or organizational data for transferring data to a data warehouse. SAP Event Management saves the information in a string format with a maximum length of 255 characters.

Control parameters save selected information in a string format with a maximum length of 60 characters.

We deliver control and info parameters. You can, however, create your own.

SAP Event Management saves control and info parameters as different data records in a data container that has the following structure:

  • Parameter name

  • Index

  • Parameter value (string)

  • Length

  • Original data type

System Parameters

SAP Event Management saves system parameters in their own database fields in the event handler extension table in Customizing. You can define your own system parameters using this extension table and you can then change the value, if necessary, using activity method Updating Field Value in Header Extension Table (HDR_EXT_VALUE_UPDATE).

You store the field values for your typical search queries as a record in the event handler database table in Customizing, and set up a targeted index for these fields.

Rule Processing Parameters

SAP Event Management saves rule processing parameters as different data records in a data container that has the following structure:

  • Parameter name

  • Parameter value (string)

  • Length

  • Original data type

Integration

The interface between the application system and SAP Event Management uses a mapping process to transfer the parameters from the application system to SAP Event Management (see Data Transfer from the Application System).

SAP Event Management uses parameters to change event handlers, for example (see Event Handler Updating).

The Web interface displays parameters and other event handler data.
