Insertion failed:

Once the database table is redirected to a CDS view, the database itself is not supported to be changed by ABAP code. See this example below:

I have a CDS view Zp_Mara_Redirect and its corresponding database view is zmara_cds.

When I try to insert some entry to CDS view, I get following error message:

According to this wiki, write back on CDS view is not supported:

When I try to insert some entry to CDS view's underlying database view, still not possible either.

And also it is defined in ABAP help that only read operation is supported. For other operation like write, you have to still use original database table.
