Posted on by Deya Saleh

can anyone give me an example of Workflow that includes "SubWorkflow" I didn't find a situation that i can use it for, and if I wanna select SubWorkflow from another module, the document key Field DropDown selection will be empty and there is no data to select to continuo the process, So i need an example where i can use SubWorkflow in Dynamics 365 Finance and Operations Workflows.

Hi Deya,

Can you elaborate on what you want to achieve? Which workflow type do you want to link with what sub workflow?

Probably you can read the AX2012 documentation as it is still the same: docs.microsoft.com/.../configure-a-subworkflow

Let's say that i need to do a loan items work flow and i wanna use subworkflow to go or initiate a workflow on procurement,

My question here can i do that?

The other question if i can't. Why this subworkflow is existed if i can't use it on another workflow with no relation between them!!

Hi Deya,

Sorry your business case is not very clear. Why exactly you want to use Subworkflow. Would appreciate if you can share some more detail about your business case to understand your requirement.

WHERE TO USE SUBWORKFLOW: When you have many conditions and approvals in one workflow, let's say PO has 100 of lines and each line has different conditions and approval hierarchy, In that case, we use subworkflow.

Please find the below link to configure subworkflow in AX 2012.

That means it's for simplification if i have a complex workflow,

The situation that i said earlier in details is, that i need to lend an item to an employee and on one of the "loan item workflow" steps a manual decision if i have this item on stock or i have to buy one. So if i have to buy one, can i select a subworkflow the workflow steps includes a PO workflow for that item to initiate it automatically??

You said it's for complex workflow, can i use a subworkflow that is different than the workflow it self (( parent Purchase requisition Workflow & Purchase order Subworkflow)) in the same workflow.??

Hi Deya,

Yes You can do that. Parent would be loaned item workflow and PR or PO can be setup as subworkflow to purchase an item but the thing is someone has to create a purchase order with all details (Product, Qty, price, vendor) then you can trigger that automatically as subworkflow. PO Details will not be filled up automatically. How would system know to which vendor you want to issue that PO.

If you want to automate complete process then you have to use power automate and logicapps.

Hope it clarifies.

Hi Deya,

We don't select specific PO number as subworkflow but we select PO Workflow ID and both are different things. There could be 100 Purchase Orders in the system but might be PO workflow will be same to approve these PO's unless and until if there is any exceptional case.

From your business case i don't think you need subworkflow. As i suggested you in my last thread, if you want to automate PO creation process that will be triggered from Employee Loaned item screen based on item unavailability then you should go for Azure logic apps. Do you have a developer around you?

Good evening, in the thread of this case something similar happens to me with the workflow of the purchase contract I have a main flow that, under some conditions, it calls sub-workflows.

To call each subworkflow, I indicate the subworkflow and it forces me to enter the document key ParentPurchaseAgreementID_PSN

The problem that this field is not reported and does not find the context.

Stopped (error): X++ Exception: Failed to find subworkflow data
at SysWorkflow-submitSubWorkflow
SysWorkflow-submitSubWorkflows
SysWorkflow-save
SysWorkflowQueue-resume

X++ Exception: The workflow system could not access the business document data. Report this issue to

your system administrator.

at SysWorkflowDocument-assertAsUser

SysWorkflowDocument-assert

SysWorkflowDocument-assertPermission

SysWorkflowDocument-getDocument

SysWorkflow-submitSubWorkflow

SysWorkflow-submitSubWorkflows

SysWorkflow-save

SysWorkflowQueue-resume

Anyone have any ideas?

Regards,
Adolfo
