• Instructions to fork and to join orders to enable parallel processing in a workflow.
• The Fork Instruction allows to create the creation of a number of parallel branches that process any further instructions and jobs.
  • The max. number of parallel branches is limited to 15.
  • Branches can include any number of instructions and jobs.
• When an order enters a Fork Instruction then for each branch a child order is created for each branch . Each child order will pass the nodes in the respective its branch independently from of the other parallel child orders.
• While child orders are running, the parent order waits for its child orders to be completed, i.e. to arrive with at the Join Instruction. The parent order therefore is assigned the WAITING state, see JS7 - Order State Transitions.
  • If a job in a child order's branch fails then the child order will be assigned a FAILED state. Such child orders require user intervention to resume, to suspend or to cancel child orders.

• The Fork Instruction is used for two parallel branches, the names of the branches can be specified.
• After the child orders for both branches are arriving have arrived with the Join Instruction then the parent order will continue with the next node.
