Add-Ins menu not visible in Crystal report for Sap Business One

Hi,

I have installed the Crystal Report Design for Sap Business One on my customer server.

But when I open the Crystal Report I can't see the Add-Ins menu to put the rpt directly on my Sap Business One.

I have installed it on many customer, but only with this I have this type of problem.

There is some restriction on Sap Version/Patches or Authorization Users or some check that I have to set on Sap or on Crystal Report?

Regards

Marco
