Introduction

• A given workflow A starts 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.
  • The ExpectNotice Instruction can be used immediately after use of the AddOrder Instruction.
  • The ExpectNotice Instruction can be used at any later node in workflow A.
    
    

When clicking the AddOrder Instruction the workflow can be selected to which an order should be added:

The ExpectNotice Instruction allows to select a Notice Board.

First upload the example from the below chapter Notice Board to be able to select the relevant Notice Board like this:

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 expecting the Notice.
  • A number of workflows can wait for the same Notice from a PostNotice Instruction.
  • The same Notice from a PostNotice Instruction can be issued by any number of workflows.
  • 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.
    
    

The PostNotice Instruction allows to select a Notice Board.

First upload the example from the below chapter Notice Board to be able to select the relevant Notice Board like this:

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 from the ExpectNotice Instruction in workflow A and the posting order of the PostNotice Instruction in 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.
