Hi Sahir,
Thanks for the prompt reply.
For our scenario, the transfer of values should happen only from formA to FormB.
which works well when process is initiated and sent to approver.
However the transfer of values from formA to formB is not done when author sends back form to approver.
We did debug method CHECK_FOR_REINITIALIZATION of class CL_HRASR00_PROCESS_UI_EVENTS it looks like sap is not executing mapping of values when it displays approver workitem for the approval, rather it is reading old work item data .
We also checked scase data , xml does exist with updated values.
The note 2061583 is applicable for
When BACK TO AUTHOR is clicked in an APPROVAL step, the updated field values are
not displayed in the form.
i.e for our scenerio, we dont need any data to be sent from formB to formA so this note is not applicable for our scenario.
