Typing fault variables

A fault variable stores data in the event of a standard or a system fault.

1. Create the new type as follows:
   1. If there is no existing library, create a new library called FaultType by clicking File > New > Other > Library.
   2. Right-click your process module and select Open Dependency Editor. Click Add and select the library from step 1a in the list.
   3. Create an XSD file called bpcfault.xsd by clicking File > New > Other > Simple > File.
   4. Paste the following text into the editor and save it.

      <?xml version="1.0"?>

      runtime fault to specify the variable type.

                      <xs:sequence>
                              <xs:element name="faultName" type="xs:string"/>
                              <xs:element name="faultNameUri" type="xs:string"/>
                              <xs:element name="messageText" type="xs:string"/>
                              <xs:element name="rootException" type="xs:string"/>
                      </xs:sequence>
              </xs:complexType>
      
      </xs:schema>

2. Create a variable and point to the XSD file.
   1. In the tray, create a new variable by clicking the plus symbol () beside the Variables area.
   2. In the properties area, click the Details tab.
   3. Select Data Type, and click Browse.
   4. In the Data Type Selection window, click Show all XSD types, browse to StandardFaultType, and click OK..
3. Determine the catch element (that exists within a Fault Handler) that you would like to associate with the new fault type. In the Details tab, browse to the newly create fault variable.
