Multiple use of text tables

Hi,

I have to use same table/attribute view multiple times in HANA calculation view.

What is performancewise best way to implement this.?

e.g. I have 4 material field in fact table. I want to join it with MAKT table.

Do Ineed to use table 4 times? or using once and creating multiple projections etc.

Is there any better way to do this?

Thanks.

Sunil
