Introduction

The

...

PostNotices Instruction is used to create a

...

number of Notices for JS7 - Notice Boards.

...

The Notices will be waited for by

...

the corresponding JS7 - ExpectNotices Instruction from the same or from different workflows.

• A workflow can include any number of PostNotice PostNotices Instructions to post notices Notices to the same or to different Notice Boards.
• Posting a notice Notice does not block further execution of an order in a workflow. The order continues immediately having posted the noticethe Notice.

Starting from release 2.4.0 the PostNotice Instruction is replaced by the PostNotices Instruction allowing any number of Notices to be posted from a single instruction. The JS7 handles compatibility and automatically converts existing PostNotice Instructions to PostNotices Instructions.

Notice

• A Notice is considered an event that the ExpectNotice ExpectNotices Instruction is waiting for. One or more corresponding PostNotice PostNotices Instructions create the Notice from the same or from different workflows.
• Both PostNotice PostNotices and ExpectNotice ExpectNotices Instructions reference a common Notice Board identified by its name. The Notice Board implements expressions for the PostNotice PostNotices Instruction and for the ExpectNotice ExpectNotices Instruction to identify a common Notice ID. The Notice ID typically is identified from a common part of each Order ID of the posting and expecting orders, for example, from the daily plan date.
  • Example
    • An Order ID #2021-07-24#T7142453954-myOrder1 is running in a workflow and meets a PostNotice PostNotices Instruction. The Notice Board referenced by this instruction includes an expression for the posting order to create a Notice ID based on the daily plan date included with the Order ID. The expression extracts the date from the Order ID, i.e. 2021-07-24, and makes this date the Notice ID.
    • An expecting Order ID #2021-07-24#T7142454683-myOrder2 meets an ExpectNotice ExpectNotices Instruction in its workflow. The instruction similarly applies the expression from the referenced Notice Board to create a Notice ID. In most situations the rule about what to extract from an Order ID is the same for the posting and the expecting orders.
      • If both instructions identify the same Notice ID, i.e. the daily plan date 2021-07-24, then the expectation is met and the order proceeds with the next step following the ExpectNotice ExpectNotices Instruction.
      • If the expectation is not met, for example if the Notice has not yet been created by a posting order, or if the daily plan date of the Notice ID of the posting and expecting orders is not the same, then the expecting order will wait until a matching Notice becomes available.
• Any number of workflows can implement PostNotice PostNotices Instructions and ExpectNotice ExpectNotices Instructions referencing the same or different Notice Boards.

Workflow Instruction:

...

PostNotices

• This instruction can be put at any position in a workflow, including nested instructions such as the JS7 - If Instruction, JS7 - Try-Catch Instruction etc..
• This instruction has a single property: the name of the Notice Board.

The PostNotice PostNotices Instruction is managed from a workflow in the Configuration view of JOC Cockpit:
