Avoid Over layering in Development of Workflows on Existing Form


Workflow Extension (alternate way)



As we all knows that over layering is restricted by Microsoft in D365FO and in extension canSubmitToWorkflow not working at all.


Last week, I have received the requirement from my project manager to create custom workflow on Transfer order form. as i mentioned that over layering is not allowed. After few hours of brain storming within team we decided to create custom workflow with new table which we will use sort of extension and associate the table with Transfer order form.

Following are the steps to create custom work flow and associate with existing form.

Prerequisite.
Basic workflow knowledge required. 


Step-1 Create custom Enum or you can use existing.

Step-2 Create custom table and add two fields Transfer order Id and Status field extend both fields with appropriate Enum or EDTs. In our case Table name is SLD_TransferOrderWorkflow

Step-3 Create relation on Invent Transfer table and our newly created table on the basis of Transfer Order Number.

Step-10 Place proper labels on workflow types, approval and menu items.

Step-11 Build the model and perform the database sync.

Step-12 Now navigate to workflow form of your module and click on new to create new workflow.

You can check in the below screen shot my workflow is appearing.

Step-13 configure workflow as per your requirement and activate.

Step-14 Create extension of the form on which you want to associate workflow. in my case form was inventTransferTable.

Step-15 Add data source table and join with parent data source. in my case parent table was inventTransferTable.

Step-16 Only two type of join supported. Inner and outer.. in my case i am using inner because i don't have previous records.  but recommend outer join if you have previous records.

Step-17 Now override the initialized method of the newly added (SLD_TransferOrderWorkflow)  data-source  and enable the workflow.

Step-18 Now override the parent tabl Methode OnWritten and insert the record on our newly added data-source as well. Whenever user create or update Transfer table.  In my case invent transfer table was parent.

 Step-19 Now build the model and create the new transfer order and verify. for me its working fine without over-layering.
