Hi Sebastian, Thomas,
Thank you for your quick response. It helped me a lot.
Today I encountered the problem that SAPGUI 740 is not working well with older versions of SAP (ie SAP ECC 6.00 / AS ABAP 700). Login is no problem but methods of global classes cannot be maintained fe. I will post this as discussion in SAPGUI area.
best regards,
Roelof Jan
