Different between GR value and service entry

Hi All,

I've one service entry sheet with 2 line (qty of 1st line is 0.5 and 2nd line is 0.5) and the value is 466k.

However, when service entry was posted/accepted, the GR document created with only 1 line item with qty = 1 and the value is more than 466k (GR value = 853k)

I've try to revoke the service acceptance but it trigger an error (deficit of PU GR qty)

Appreciate your help,advise and comments.

Thank you.
