Hi
I have recently tried using WebDynpro (SAP Plant Maintenance) on iPAD, it works really great.
I see this posts are from 2012 and that time WebDynpro was developed as desktop version only and SAP was not supporting it on Safari, however things have changed now with Net weaver W7.03/7.31 SP9 and with SAP Net weaver 7.40 SP4, SAP Offers support of running WebDynpro in Safari on iPAD. My users are really delighted with this function.
