Workflow status got changed as Incompatible - Mendix 9.12.6

0
Hi everyone,   We have a workflow created already and a few requests created already in the system. after some time the client requested new changes in the workflow, we made the change, and all workflow in progress status changed to Incompatible, By reading the documentation, I understood that "An activity is introduced in the path that is already being executed" will create a conflict and make the executed workflows incompatible.   my question is how can I solve this as I have more than 250 workflows in progress now  its Incompatible as we in the production environment?   We tried with workflow commons module to move state from incompatible to progress by continue action but it is taking too long time to change state to in progress . it takes around 30 min for one workflow. we have around 200+ workflow   any suggestions Please to make it quickly by java  action or any other way

Hi Muthu, 

As per the Workflows' Conflict Mitigation Matrix, Restarting the Workflow and Jumping to specific activities are possible solutions.

 

In the past, just like you, I used the available Workflow Commons' tools to fix Incompatible Workflows but in my case, it was quite fast.

 

Please note that there's a maximum number of workflow instances that can be processed simultaneously. This can be configured in the App Settings > Workflow. Is it possible that the Workflow you saw taking 30 mins was in fact just in queue waiting to be processed?

Hi,Muthu Kader Sahib Badhul Ashab

Kindly retrieve all the workflows using the Workflow Retrieve activity. Once retrieved, please pass the list into a loop. Within the loop, you can use the Change Workflow State activity to update the state and continue the workflow accordingly.

For better clarity, please refer to the image I have attached, which shows the placement of the retrieve, loop, and change state activities in the microflow.
