Functional Prerequisites for Message Determination

Use

Message determination is used to issue messages for agency documents in Agency Business, and the billing document type is used to control how this is done. The following settings must be maintained for this in Customizing for the billing document type:

• Message determination schema for header messages
• Message type for header messages
• Message determination schema for item messages
• Message type for item messages

It only makes sense to define a message determination schema and a message type for item messages if the document is a list, that is, a settlement request list, posting list, or remuneration list.

In the condition technique, message application WR is used for Agency Business.

Message determination uses the condition technique. Below is a brief overview of the elements and settings that are required in Customizing for Agency Business.

• Condition tables

A condition table defines the combination of fields for which message records are created. Standard condition table 170 controls message determination dependent on the combination of purchasing organization and vendor, for example.

In addition to the standard condition tables, you can define your own condition tables.

• Message types

In the SAP System, the message type is used to map various messages such as the printout of an individual document or the printout of a document list. In addition, the message type defines which transmission medium is used, and when and to which business partner the message is sent.

In addition to the standard message types (such as WKAM and WPAM for vendor billing documents with logistics data), you can create your own message types.

Condition records must exist for the message types, so that default values are available for the transmission medium, business partner, transmission time and so on. For further information, see Creating Condition Records.

• Access sequences

Access sequences are search strategies that the SAP system uses to find valid condition records.

In addition to the access sequences, you can define your own access sequences.

• Message schemas

The message schemas contain the permitted message types for the various document categories in Agency Business. This enables a default value to be generated for the messages that belong to the agency document. In addition to the standard message schemas, you can define your own message schemas.

In addition to these elements of the condition technique, the following settings must be maintained for message determination:

• Message types must be assigned to the partner functions.

The permitted type of message processing (such as printing or faxing) must be entered for a particular combination of message type and partner function.

• SAPscript forms (for printing and faxing) and programs must be assigned to the individual message types.

The forms control the layout of the output documents, and the programs control message processing.

In the standard system, a program and a form enabling print output are already assigned to each message type.

You can choose Define forms to change existing forms and create new ones.

• You can choose Assign form texts to define which texts for address, letter header, footer, and style of greeting appear in the output document, dependent on purchasing organization, sales organization, and company code.

• You can define print parameters dependent on the following keys:

• Sales organization/distribution channel/division
• Sales organization
• Purchasing group
• User
