Description:
This guides you to disable the validation for the activities you want or disable any validation. Test with attached process (Filename:TestValidate.zip) which contains a mapper and asks for an Integer but gets a string. It works if you disable any validation. Note: You must put the properties in properties.cfg. It does not work if put in designer.tra.

Click "Advance" before testing a process in Designer. Input like "-p F:\tibco\designer\5.9\properities.cfg" for "Test Engine User Args").

---------------------------------------------------------

1). For Mapper activities you can set the following properties:
-----------
Validate.Output.Task..=false
Validate.Input.Task..=false
-----------

Based on the same sample if the activity is inside the group called 'Group', use the following syntax:
-----------
Validate.Input.Task../=false
Validate.Output.Task../=false
-----------

In case there are white spaces in the activities names, they should be escaped with a backslash character in BW.

Validate.Input.Task..Activity\ Name=false
Validate.Output.Task..Activity\ Name=false

2). For Start/End activities of sub-processes:

Validate.Input.Task.Parent.process.Call=false
Validate.Output.Task.Parent.process.Call=false

3). To test, you could disable any validation:

Validate.Input.Task..=false
Validate.Output.Task..=false
Validate.Input.Task.*=false
Validate.Output.Task.*=false
