For Journal Entry there is one option available in client data and it is specific to the Post Transition. When configuring the transition that connects Approve to Post or Submit to Post (if your workflow also supports that path), you must select the Post Journal Entry setting, this setting will perform the posting to atrieveFinance. To set the value, click on 'select value' and select 'Yes'. Note that at least one transition needs to have the Post Journal Entry client data set. If this is not set, then a warning will display.
