Have a userevent script on sales order, in which we are creating a task and calling a MR script based on some logic. Now the MR script is already running so the userevent is throwing an error: MAP_REDUCE_ALREADY_RUNNING", How to get around this

you can create multiple deployments on the MR and not use the deployment id option in the task method. By not explicitly calling a deployment it will grab the first available deployment

Cool thank you

You can also dynamically copy deployments.
