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.

 Right-click in the header part and click External File Type Parameter 
  Definition to launch the 
	External File Type Parameter Definition 
  window.
- Use the Available Parameters tab.
- Click New.
- Define the parameter number. The number defines the 
  order in which the parameters will be presented in the 
	External File Assistant.
- Define the parameter identity. The parameter 
  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.
- Supply an enumeration method in the Enumerate 
  Method field if available values should be displayed as a drop-down list 
  during input in the External File Assistant.
