Execute workflow autocustomizing
In this section you perform workflow Auto
Customizing. This is where the basic settings for the workflow are made, which
are prerequisites for IDoc processing. Settings that have already been made
are not overwritten by Auto Customizing. For detailed information see the
document 
Standard settings for SAP Business Workflow
Activities
When performing the activity, the next screen to be displayed is Verifying Workflow Customizing . Choose Automatic Customizing from the screen.
Further Notes
You must perform workflow Auto Customizing in the production system as non-transportable settings are made here. You can execute Auto Customizing as often as required as it does not change existing settings.
