STOCKHOLM, Oct 13 (Reuters) - German business software group SAP (SAPG.DE) raised its full-year outlook for a third time on the back of a strong showing in the third quarter as more customers shift their IT operations to the cloud. SAP now expects cloud revenue to grow by 16%-19% in the year as a whole, helping its overall cloud and software revenue to gain by 2%-4%, it said in a statement late on Tuesday. Operating profit is expected to be flat to down 2% for the year, an improvement from its earlier forecast of unchanged to down 4%. SAP, which is moving to subscription-based cloud services from software licences with up-front fees, launched Rise with SAP, an all-in-one digital transformation package in January. "We see record adoption of our applications and our platform," Chief Executive Officer Christian Klein said in a statement. "This has resulted in strong acceleration of our cloud growth." SAP raised its forecast for cloud and software revenue for the full year by 200 million euros to 23.8 billion-24.2 billion euros. The cloud backlog for flagship database S/4HANA was up 58% at constant currencies and current cloud backlog - a measure of incoming business - reported a 22% growth during the third quarter. Adjusted revenue rose 5% to 6.68 billion euros ($7.70 billion) for the third quarter ended Sept. 30, the company reported in a preliminary earnings statement. SAP is expected to release full results on Oct. 21. Adjusted earnings per share rose 2% to 1.74 euros, backed again by its profitable venture capital investments, Sapphire Ventures.
