Unicode compatibility ABAP Error

Hi All,

I am trying to read a ABAP CDS view and write it on to a ZTable due to some performance issues. (It is historical one time load data, I don't need this to go thru transformations every time when the reports are invoked). When I try to check the program I get an error at the INSERT statement complaining about my defined structure is not unicode compatible.

I have added my simple program with a screen shot can you tell me how to fix this error.
