Regarding with deduction issue
If you see overtime status on system now you will see that showing “ Waiting for submit “ but recorded has been transfer by me[ Kamonrat]
That seem like user has been rejected records on this day and recreated OT record after HR user transferred OT record to SAP
However, right now you already got overtime hour on 20 Sep but you need to submit leave and overtime adjustment form to me for adjust your shift and next month you will be got money back
About form I already attached file to you
