CallSQL equivalent in B1iSN?

Hello.

I was trying to get all rows from a table in the receiver system. As I need all the rows and not just a single one identified by Code I cannot use KeyExpansion (right?). I remembered the CallSQL atom type from B1if. To my surprise this type is not listed in the dropdown of the 'Add a new atom' dialog. Now, how can I read all rows from that table in the receiver system and include them in the message so the final atom can use the data for processing?

Regards,
