Operating margin dropped to 28.0 percent from 29.8 percent a year ago. The decline reflected increased investments in SAP's newer cloud-based software services, where revenues from new sales come later in the form of subscription payments.
SAP Chief Financial Officer Luka Mucic told CNBC Tuesday that he was pleased with the results for the cloud business, however.
"What is very pleasing for me from a CFO perspective is that we were able, for the third quarter in a row, to sequentially raise the gross margins in the cloud business," he said.
Mucic said the cloud business was profitable and that he was "quite happy" with its trajectory. "The cloud is becoming a more...meaningful part of our entire business," he added.
A Frankfurt trader said software licences and profit margins were among the factors likely to disappoint investors. "Expect a volatile but at the end negative share price reaction," he said.
SAP is battling alongside established U.S. software makers such as Oracle, IBM and Microsoft to boost Internet-based software sales and fend off pure cloud-based rivals Salesforce.com, Workday and, less directly, industry pacesetter Amazon.com's web unit.
Salesforce.com in May raised its revenue forecast for the full year, after the cloud software company reported a profit for the first time in seven quarters.
SAP's cloud subscription and support revenue from continuing operations jumped 129 percent to 555 million euros from 242 million euros in the second quarter of last year. On the same basis, revenues from its mainstay software licence business rose 13 percent to 3.51 billion euros from 3.12 billion euros.
Without currency effects, software licenses grew 3 percent.
SAP stuck to its outlook for the full 2015 year for non-IFRS operating profit of between 5.6 billion euros and 5.9 billion euros at constant currencies, which represents flat growth to a rise of as much as 5 percent from 5.6 billion euros last year.
SAP shares are indicated to open 1 pct lower, according to premarket data from brokerage Lang & Schwarz at 0540 GMT. The German blue chip index is indicated to open 0.3 percent higher.
