Dear Maneewan,
I had checked : 90880GD011A4R9-003
SSG6513 - no such glass delivered but you GR under PO8800013737 and this had been take in by account and can't be reverse anymore.
SSG6515 - is the actual delivery for PO8800013737 but you GR under PO8800013600.
As such, although swapping acceptable but additional glass GR without physically receive it, i can't advise you further action can be taken. Please update us how are you going to deal with it and we will take note from there.
Thanks.
