Ok, thanks @RandyHayes @phipps0218 @SanshubhLubal
First, I have to reorder thing and put this symbol ( > ) per item... Such that OnSelect ( > ), it shows the item in each row respectively, in the Takeout Form

Secondly, when any value is inputted into Take Qty, let it subtract from SAP Qty. Also, at Safety Stock (44) which is, a point where the SAP Qty is now 44 (matching Safety Stock value), let it trigger email in every 24hr circle to Email of user with Permission level Store Supervisor.
Finally, I want to Patch the records to the existing records to update selected item.
I hope this is not too much to comprehend to provide a solution.
Thanks guys
