How to keep buffer in cloud app?

Hi all,

In SAP GUI, user's behavior creates some buffer data and the buffer will be saved into db when user clicks save button.

I am wondering how this works the same in cloud Fiori app, as far as I know, RESTful API is stateless and there is not something like session.

Regards.
Eric

In classical ABAP programming so called LUWs are used (Logical Units of Work). In short they are keeping changes and either push it to DB after COMMIT is called or are cleared with ROLLBACK. Documentation from SAP on the topic: SAP LUW

As for cloud computing you can refer to the blog to check differences: The SAP LUW in ABAP Cloud
