Select on Foreign Table with JDEBASE

I have a BF than open a foreign table (specs non known by JDE) and i want to select. I use the JDB_SetSelection as the foreign table is a World's one but it faild.
I don't find why, anyone's Ideas ?

Hello Serge,
Not a lot of information in your post, but did you use the JDB_OpenForeignTable api to generate a request handle for JDB_SetSelection ?

yes i did and i also try to use to construct my own select and replace select by JDB_SetSelectionX.
Nothing i tried is working.
