Introduction

  • A given workflow A starts a workflow B by use of the JS7 - AddOrder Instruction.
  • Workflow B runs asynchronously and in parallel to workflow A.
  • Workflow A should wait for completion of workflow B.

Solution

Workflow A

Download (upload .json): pdSequenceAddOrderSynchroneously.workflow.json

Workflow A is designed like this

  • The workflow executes a number of jobs and an JS7 - AddOrder Instruction for workflow B.
  • Starting from the AddOrder Instruction workflow B runs asynchronously and in parallel.
  • Subsequently a JS7 - ExpectNotice Instruction makes workflow A wait for completion of workflow B.
    • This can happen immediately after use of the AddOrder Instruction.
    • This can happen at any later node in workflow A.

Workflow B

Download (upload .json): pdSequenceReceiveOrderSynchroneously.workflow.json

Workflow B is designed like this:

  • The workflow executes a number of jobs and a JS7 - PostNotice Instruction.
  • The PostNotice Instruction sends a signal to any workflows waiting for the Notice.
    • A number of workflows can wait for the same PostNotice Instruction.
    • The PostNotice Instruction does not necessarily have to be used as the last instruction in a workflow. In fact it can be used at any position in the workflow.

Notice Board

Download (upload .json): pdSequenceSynchroneously.noticeboard.json

The Notice Board is configured like this:

  • The Notice Board specifies the same rule to match the expecting order of workflow A and the posting order of workflow B.
  • The selected rule Matching Daily Plan Date specifies that both orders of workflow A and B have to be in scope of the same Daily Plan date.
    • It is a frequently used rule to match orders only that are created for the same date.
    • The Notice Board offers to use more complex rules, for example to match the Daily Plan date and the names or orders that can be specified when adding orders.
  • The Notice is assigned a lifetime. The expecting order in workflow A should pass its ExpectNotice Instruction node within the lifetime of the Notice.
  • Users have the option to manually add Notices from the Resources->Notice Boards view and they can delete Notices from the same view.
  • Find details from JS7 - Notice Boards.
