Hi Moises,
You can check at SAP support as various notes are available for the same issue. Example SAP note
1564780 - Update termination during update of schedule line in PO
1742144 - J_3ABSSI is not updated upon editing confirmations in a PO
In search criteria put "Error updating table j_3abssi" and application area as IS-AFS-MM*. Check SAP note valid for your version.
