Update main workflow container from In-Progress Subworkflow
I have a requirement where I need to update a main workflow container element from a sub-workflow, while the sub-workflow is still running. (In-Progress)
I have tried using the FM SAP_WAPI_WRITE_CONTAINER in sub-workflow, but it returns an error saying "Cannot call WAPI interface 'SAP_WAPI_WRITE_CONTAINER' in this context".
I have also tried FM SWW_WI_CONTAINER_MODIFY, but it does not update at all.
I have also tried triggering an even in sub-workflow, which in turn triggers a class method, but it gives an errors saying "WF locked"
Please let me know if you have any other strategies.
