Message /SCMTMS/AC 102 You are not authorized to perform this action... Only on my laptop

Hi,

I am working on SAP TM 9.0

When i try to change a freight order only on my laptop, i have the following message :

/SCMTMS/AC 102 : You are not authorized to perform this action for the business document

I can create or display a freight order.

I don't understand is why I can change a freight order on another laptop ?

The problem occurs only on my laptop, so it is not an authorization issue.

Your help will be really appreciated.

Best Regards
