Use the Run VBScriptThe Run VBScript tool is used to create a task step that runs a Visual Basic Script using data produced by other steps in the task. function to write your own Visual Basic (VB) functions, for example, to change input date formats from MMDDYY to DDMMYY before being passed to another task step.
Run VBScript functions are available as part of the Data Transformation Layer (DTLWhen used as part of a BPA Platform tool, the Data Transformation Layer (DTL) extend the tool's functionality by transforming SML from schema to another. In addition, several transformation functions are available for use with the input data before such data is mapped to the destination schema.) feature.
Adding a Run VBScript Function
Run VBScript functions are used in the Mapping tab of the following tools:
|||Run Microsoft Reporting ServicesThe Run Microsoft Reporting Services tool automates the running of Microsoft Reporting Services (MSRS) reports.|
|||Transform DataTransform Data is a Format tool that enables a new structure to be created from an existing XML or recordset data source. The output generated by this tool is ready for use in a destination system which consumes or requires XML.|
|||Web Service Connector|
- Open the relevant task step and go to the Mapping tab.
and — Node or element available for mapping
— Mandatory element that must be mapped and included in the output
- Click Functions to expand the Functions pane.
- Expand the
Datanode and drag Run VBScript to the Transformation Mappings pane.
- Drag the relevant Input Data source node
or elementto the new icon.
- Do the same for the receiving Output Data node
- Double-click the icon.
The Transformation Mappings pane is replaced with the Run VBScript's configuration pane:
- Enter a meaningful Function Name.
- To change an existing mapping, either Inputs or Output, use the drop-down lists under Mapped To to select a new node
Adding the VB Script Function
Go to the VB Script tab and add the code for the function. Use Check Syntax to check for errors.
Selecting Error Handling Options
Use the Options tab to define error handling behaviour for this function.
At task run-time, if
|||Output an empty String — An empty string is passed to the mapped output node at task run time, for example,
|||Output no Data — The element isn't included in the output XML.|
|||Output Value — Enter a static value in the provided text box; this value is passed to the mapped output at task run-time.|
|||Error — The function logs an error to the BPA Platform Event Log. Depending on the parent task step's own error handling options, the task can either continue or fail completely.|
Click OK to save the function and return to the parent task step's Mapping tab.
