Splitting up a large workflow using External Signal

Hi,

I have a large complicated workflow which runs at the end of each campaign which summarises findings and then emails this to stakeholders.

Ideally I want to split this into two parts, the simply delivery part and the complicated summarisation part. The simple part will allow the operators to select their data and delivery templates and send the email. The complicated part does a ton of analysis work and delivers some files. The operators should never touch any of the complicated part.

I was thinking to put a signal at the end of the simple part which after X amount of time will trigger the complicated part, passing through the required variables to enable it to determine the campaign it needs to analyse and deliver the automated reports for.

How best to do this? I looked at signals and I think this is the best way, however I'm unsure of exactly how to trigger a signal from a workflow. 

 

Appreciate your input!

    Hi Alistair,

    Signal seems to best suit your requirement. 

    Each signal activity has an internal name and this is something which helps trigger the signal.

    So at the end of simple part you can put a JS code activity.

    Use the following code

    xtk.workflow.PostEvent('Identifier or internal name of the workflow which contains signal activity', 'The name of the activity from which the event starts', 'The name of the transition to activate. If this name is empty, the event will be issued on the first valid transition', 'The parameters of the event in the form of an XML element. The name of the element must be variables.', 0)

    Hope this helps.

    Regards,

    Vipul

    Hi Vipul,

    Would you be so kind as to show an actual example where a variable (such as a delivery Id) is being passed through?

     

    Thanks!
