Customer Exits

Use

Customer exits in the inbound function module allow customers to:

• Change the way SAP segments are processed, for example, by changing the value of fields

• Access the customer segments they added to the SAP IDoc using the IDoc definition tool

The following points should be fulfilled by the customer exits:

• Can all the data in SAP segments in the IDoc be read via customer exits?

• Can all the customer segments in the IDoc be read via customer exits?

• Is a customer exit called every time a segment has been processed?

• Does the customer exit support error handling?

• Can the exit fill the parameters Workflow_Result, Idoc_Status, and Return_Variables?

• Is there a customer exit for serialization?

• This is useful if the inbound function module does not support serialization.

• If the customer has appended fields to an SAP table, are these fields easily accessible in the exit?

• Are the exits long-lived? Customers expect exits to be called with the same meaning in future releases.

• Is it easy for the customer to navigate through the data in the exit? For example, to determine which item us currently being processed, and so on.

• If the same coding is used for different message types: Can the customer identify which message type is being used?
