Control Your Output Messages with PPF Technology

Post Processing Framework is a technology introduced with Web Application Server that triggers a workflow for message output. Here’s how to configure it with just a few simple steps.
Post Processing Framework allows you to process actions for different output types such as printing, sending emails, or faxing using Smart Forms. Since SAP applications work on the document concept (i.e., they generate documents for key business events or processes), they can also trigger a workflow or user exit to perform functions based on the conditions you configure. This technology replaces the output control in R/3 with a wider functional scope that is simple to maintain, use, and connect to another SAP system, a non-SAP system, or any other subsystem.
Post Processing Framework (PPF) technology is a
uniform interface available since SAP R/3 Enterprise
Release 4.7. Part of the SAP Web Application Server
(Web AS), PPF can trigger workflow for email, fax,
and print, or can call another method, such as sending
data to another subsystem. The actions are based
on the conditions that you configure.
PPF has tools for scheduling, starting, and monitoring
actions. Determining, generating, and processing
actions can either take place automatically or with
user interaction. A condition trigger could be a
preset condition the system can look for, such as
a price higher than a certain amount, or it could
be based on a user action, such as an approval in
the case of workflow.
I’m going to show you how to set up actions
that trigger application documents. The system
supplies some samples, so you can use Copy
with Reference and make your own changes
to predefined configurations, or you can take
the approach of creating your configuration from
scratch using the wizard. I’ll explain
the two methods:
- Create and modify PPF directly in the Web
AS configuration in the application area. I’ll
start with the customizing steps, as they explain
the configuration from the application point
- Create a PPF definition using the wizard,
a quick setup tool that focuses on the technical
setup of the PPF. Using a wizard, you get the
same results in terms of the technical settings
for the PPF configuration as if you had used
the configuration steps directly. The wizard
provides application area detail and pre-populated
information and it is the best practice. It
can help when you create a new action that
differs widely from those you already have.
The wizard, however, helps you perform the
definition only — you must do other associated
configurations directly in the application area.
