Why, just....why?
Its always amazed me that something so ugly, so cumbersome, un-user-friendly, complex, difficult to maintain, update, fix or manage is the top software time after time in reviews of ERP's and related systems.
I worked out the SAP business model long ago... make something SO complex that once someone's bought it, its just going to be too expensive and awkward to migrate off to something else.... h^ll - even its own version upgrades are the stuff of worst nightmares.
Nearly ever customer bastardises SAP out of existence - why - because SAP allow it.... brilliant strategy.... customers are tied to them forever.... easier to close the business and move to a new one than try to migrate off of SAP.
Do SAP care about cloud? No. Not really - they want their fingers in it just incase - but their focus is, and will remain in the huge money generated off of licencing.
