Multiprocessor Process Custom Task Sequence

I want to set a specific work position for the operator when working on a multiprocessor.

Normally, when I need to do this with single processors I use a basic custom task sequence, but in this model I need to use multiprocessors.

I thought the logic would be similar, but when I use the same task sequence I have found that the operator keeps busy and is not being released when the process has finished.

I guess the pick operator logic is not the same on the processor and on the multiprocessor but I haven't been able to find any information in the manual

In the attached model you can find a processor with the custom task sequence that is working, a multiprocessor with the same logic that is not working and a second multiprocessor that is using the default custom task sequence that appears to be incorrect.

The multiprocessor does use different parameters than the processor so that exact code won't work. Instead, I was able to make the same functionality using the Custom Task Sequence Example 1 for the multiprocessor. Instead of the custom tasks being TASKTYPE_LOAD, TASKTYPE_BREAK, etc., I instead use the same tasks you had in the processor:

stopobject(current, STATE_WAITING_FOR_OPERATOR);
taskSequence.addTask(TASKTYPE_TRAVEL, current.WorkPosition, NULL);
taskSequence.addTask(TASKTYPE_STOPREQUESTFINISH, current, NULL);
taskSequence.addTask(TASKTYPE_UTILIZE, item, current);

Since this code returns 0 and won't be called again, we will "manually" release the operator with an On Process Finish trigger on the multiprocessor:

freeoperators(current.centerObjects[1], item);

This should give you the same behavior you were getting with the processor custom task.
