Expense report approval did not reflected in the system

Hi Guys,

May i ask what are the possible root cause for this issue? Thank you!

Expense report actions were not reflected on the system.

1. Submit the Expense report

2. Approved expense report

3. Return to worklist (the expense report was still showcased) and then once i clicked the approved item - refer to the screenshot below

4. Upon checking back-end. the expense report status was not updated to 'PAR'. it is still tagged as 'SUB'. On the EX_SHEET_HDR- Action field, it was indicated that the report was approved by the Supervisor. However, on the EX_ARPVL_HIST. the action was not reflected too.
