Hello. I will be glad to assist you with this. In the Test Plan module, highlight the desired BPT test and click on the 'Test Script' tab. Next you will need to click on the link displayed in the 'I/O Parameters' column. In the 'I/O Parameters' dialog box, select the checkbox in the 'Link I/O' column for each component or flow input parameter that you wish to link, which opens the 'Select Output Parameter' dialog box. In the 'Select Output Parameter' dialog box, you will find a list of output parameters from each source business component or flow in the business process test prior to the current target component or flow. Locate and select the output parameter that you want to link to the input parameter, then click the 'OK' button. Note: If the number of iterations for the output parameter doesn't match the amount for the input parameter, the parameter name will displays in red. In order to have a match, you will need to make sure that the number of output parameter iterations equals the number of input parameter iterations. Once you have linked the input and output parameters, click the 'OK' button to close the 'I/O Parameters' dialog box. I hope this helps!
