Hi Isomorphic,
please see the following docs:
I have this .ds.xml:
This is what is generated for an add-operation followed by a client side ListGrid-fetch:
Search the page for "T_ATTACHMENT.DATA," to see that it is included in two SELECT statements.
Depending on the filesize this will create much unneeded IO/network traffic between the webserver and the database.
I'm using v10.0p_2015-08-24/PowerEdition Deployment.
Best regards
Blama
please see the following docs:
