Hi,
I am using Solutionbeacons.But in the Action button the invoice validate checkbox is disabled.
In Setup>Options>Payables under Invoice Tab..i checked the Allow online Validation checkbox still the Validate checkbox is disabled.
Can somebody help.

Thanks

Pl login as sys admin and in menu find AP_APXINWKB_MENU and check if Invoice Approve is checked (Granted) or check in the responsibility if it is not excluded. Thanks
