Removing a program from O/E Transactions

SOLVED

Hello Community,

I have a customised version of the Order Entry screen (OEOrderEntry.exe) which was added to O/E Transactions panel. Then the point was to prevent users to use the original Order Entry screen (program OE1100).  I found out that I cannot delete it. Actually I could not find a way to remove it from O/E Transactions.

Would you know how to do it ?

Many thanks,

Eudes
