Define External File Type Parameters
Explanation
Use this activity to define available parameters
associated with an external file
type. The parameters are typically used when an external file is read or when an
external output file is created, and the supplied values for the parameters are
used as criteria for the process.
Available parameters are associated with parameter sets
an these sets are referred to by the external interface.
If during the input or output process a component
specific interface (API) should be called, e.g. as for external supplier
invoices, then it is up to this interface to take care of the parameters and use
them appropriately. However if the general interface (API) within the External
Files toolkit should be used, typically when creating an output file from a view
definition, then the supplied parameter values will be used as select
conditions.
Prerequisites
An external file type must have been defined.
It is not possible to add or modify parameters for system defined file types.
System Effects
The defined parameters for the external file type now
be associated with one or several parameter sets.

identity must be recognized by the interface (API) that will receive the
parameter after input.
- Define a description for the parameter. The
description will be displayed during parameter input.
- Mark the Browsable Field if the parameter
should enable launch of the general file browser in the client.
- Supply a text in the Help Text field if it is
necessary to describe the purpose of the parameter.
- Supply a validation method in the Validate Method
field if the parameter should be validated after input in the
External File Assistant.
- Supply a view name in the Lov View field of
List Of Values should be supported during input in the
External File Assistant.
