Philip MUGGLESTONE from the SAP HANA Academy and the Partner Innovation Lab just uploaded a new series of hands-on video tutorials about developing multitenant business applications for SAP Business Technology Platform (BTP) using SAP Cloud Application Programming model (CAP). In this blog post you will find the videos embedded with references and additional information. For the blog post where we introduce multitenant business applications (videos 1-10), see To create CAP business applications, an extension generator is used. For more information about how the Yeoman generator can be used in SAP Business Application Studio, see Questions? Please post as comment. Useful? Give us a like and share on social media. Thanks! |
