Hello guys,

We're trying to create a ESS Job / Concurrent to change a default buyer of an Item. For that, we want the user to select the item number, current default buyer and the new default buyer as the ESS job parameters and pass these parameters to this REST service. We've been searching for a way to call this service using an ESS job and we found that it can be done using PerlJobType, but we couldn't find any documentation on how to perform this task. Do you guys know how can I do it?
