In this Customizing activity, you define interface key fields for the determination of interface variants during runtime of the SAP Application Interface Framework.

Interface key fields defined here are available as the basis for the determination of interface variants. You therefore define a link between the field in the raw data structure that contains the key value and a field name in your variant assignment table that will be used to identify the correct interface variant for a data message.

When a data message for an interface that is customized for the use of interface variants is processed, the value of the key field will be compared to the key field's value as defined in the variant assignment table. If they match, then the corresponding interface variant is used for processing the message.

You need to have completed the preceding two steps Define Interface Variants and Define Assigning Tables.

There are no interface key fields in the delivery of the SAP Application Interface Framework.

1. Choose a namespace, interface name, and interface version.
2. In order to define new interface key fields, choose New Entries.
3. Link an interface variant key field to a field in the variant assignment table.
