DataSource with composite Key

[schefferp]

Hello,

I want to create a new dataSource for mapping a cubeGrid to a table.

But the existing table have a 4 column composite key.
How can I declare it?

On the site example it's only example with one primary key.

This feature was sponsored by your organization and is being built. We will notify you when it's done.

However, you should double-check with whoever initiated the sponsorship on your side, because there were no requirements given around CubeGrid behavior and it seems like you may be expecting something here that was not communicated.
