SAP has made an undisclosed investment in a partner company to drive growth of its NetWeaver web-based integration and application platform.

The enterprise resource management (ERP) software vendor has made an undisclosed investment in US-based Visiprise, which develops integration software for manufacturing companies that use SAP's NetWeaver platform.

The investment is designed to strengthen the partnerships around NetWeaver, including its portal, data warehouse and other components. The ERP giant didn't disclose the size of the transaction, but called it a "minority investment."

Visiprise makes software for manufacturing companies in the aerospace, defense and medical industries, among others. It has around 200 customers, including Boeing, Northrop-Grumman and BAE Systems.

The investment money came from SAP's $125 million (£84m) NetWeaver Fund ( established in May. SAP has said each investment would typically be no more than $5 (£3.4m). Visiprise is the fund’s third investment.

SAP made its first investment in August, in intelligent device management software provider Questra. And last month it invested in ArisGlobal Holdings, which makes software for the pharmaceutical industry.
