Creating and Configuring a Run-time Link

1. Create a run-time link in the following ways:
• - Press Ctrl and drag the group to a downstream transformation in the dynamic mapping.
The Run-time Linking dialog box appears.

• - To create a run-time link to a Write transformation or a reusable transformation, drag a group from an upstream transformation to a group in the reusable transformation or a Write transformation. Then, select Create Run-time Link in the Linking dialog box to open the Run-time Linking dialog box.
• - In the downstream transformation to which you want to create a run-time link, go to the Properties view and click the Run-time Linking tab.

2. In the Link Properties area, select one or both from the following options to determine which ports to link at run time:
• - Parameter. Use parameter if the port names can change between mapping runs and you know the port names. You can create a new parameter or choose an existing parameter of type Input Link Set.
• - Link Policy. Use link policy to automatically link ports by name. This option is selected by default. If the port names contain a prefix or suffix, enter the string to ignore.
3. To create a new parameter of Input Link Set type, perform the following steps:
1. a. Click New.
2. b. In the Parameters dialog box, enter a parameter name.
For example, Cust_InputLinkSet.
3. c. Optionally, enter a parameter description.
4. d. Enter a default value for the parameter as comma-separated pairs of ports.
For example, enter the default value as follows:
C_NAME->Cust_name, C_ACCTBAL->Cust_acctbal
5. e. Click OK.
4. To choose an existing parameter of Input Link Set type, perform the following steps:
1. a. Click Browse.
2. b. In the Assign Parameter dialog box, choose a parameter.
3. c. Optionally, create new parameters or edit parameters from this dialog box.
4. d. Click OK.
5. Optionally, to add another run-time link from the Run-time Linking dialog box, perform the following steps:
a. Click the Newbutton () in theLinks area.
The New Link dialog box appears.

1. b. Choose a group from another transformation in the dynamic mapping.
6. Click OK to create a run-time link.
The Developer tool creates run-time links between the groups.

7. To edit an existing run-time link, right-click the link, and select Run-time Linking
The Run-time Linking dialog box appears where you can change the options to determine which ports to link.
