Before a process revision can be built using the Production client application, you need to release it to Production.
Note:
You can move a process back to Under Construction until a unit is initialized within a related batch.
Once all required approval processes are signed-off, select the Green check mark icon in the upper-right corner of the Process Definition window to change the revision to Released to Production.
Warning!
Once you release a process revision and a unit is initialized within a related batch, it cannot be undone—any changes to the process or assembly at this stage must be in the form of a duplicate process or new process revision.
