Re: Expensive Architecture (Data Access Extension)

Hi,

interesting feedback, however i'm not personally familiar enough with SDK Data Access Extensions to comment. perhaps Alper DericiJay Xiong  Dong Pan will be along to comment later.

I had a look at the Lumira DAE SDK guide http://help.sap.com/businessobject/product_guides/vi01/en/lum_120_dae_dev_en.pdf

and it does explicitly call out "preview, edit, and refresh" as 3 distinct phases where the datasource is hit.  (there's a neat flow diagram on page 10 in the above link)

It might also be useful if you fleshed out the thinking/solution behind your "workaround which avoids two calls"

Thanks & regards,

H
