> #### 5.5.4 Define Remote Subprocess Node attributes

> Creating remote sub processes is similar to creating the subprocesses described in the previous section (hereafter called internal subprocesses to differentiate them). For more information about remote sub-processes, see Appendix F: Interstage Business Process Manager Integration with Other Workflow Servers.

> ###### To access a remote subprocess:

> 1. Display the process definition.

> 2. Right-click the Remote Subprocess Node () and select the User Defined Attributes tab to review the data you may need to link between the processes (do this for both the parent process definition and the sub process definition).

> 3. Select the Data Mapping tab. This pane will display the same functional elements as illustrated in the following figure.

> Figure 46: Create Subprocess dialog

> 4. Copy in or enter the URL of the process definition that you want to use to create your remote sub process.

> 5. Specify either SWAP or ASAP as the transfer protocol.

> 6. Use the New Data Mapping panel to map user-defined process attributes (UDAs) between the current process definition and the process definition you have specified. Using the two drop-down lists, select a data type and UDA for the parent process definition. Then, enter the UDA (for Interstage BPM sub plans) or Variable (for CollaborationRing sub plans) to which you want to map the selected UDA. Click Add Mapping.

> Note that the Parent Plan Data Items drop-down list displays all user-defined process attributes of the selected data type in the parent process definition. The UDAs from the sub process definition must be typed in. Only mapping to string type variables is allowed for CollaborationRing subprocesses. However, you can map UDAs of any type to the CollaborationRing variables.

> 7. On the Existing Data Mapping panel, select a data mapping item, and click the check boxes to indicate whether the data value passes from the parent process to the subprocess ("Input") or from the subprocess to the parent process ("Output"). Note that each mapped pair of user-defined process attributes may be set individually.

> 8. On the Existing Data Mapping panel, you may also select a data mapping item, and click Delete Mapping to remove it.

> 9. You may also use the Script tab to add Prologue or Epilogue Scripts and the Action Set tab to add Prologue or Epilogue Java Actions to the Remote Subprocess Node.

> 10. Click OK when finished.
