Field help (EXTLAB2) 

This field identifies the labor work center that is to be associated with this machine. For example, the labor work center that relates to the crew that operates this machine.

The work center site of a 'labor' work center must match the site for the routing code, if defined.

Scheduling is not carried out for labor work centers as they are considered secondary and 'always available' (or available at the same time as the main work center). Their load is managed for information purposes only using the coefficients defined for the main work center.

If the main work center is of type 'subcontracting' there is no associated secondary work center.
