Screen output without connection to user

Hi,

I have a VERY simple program, that is called by an ABAP proxy and thus in background.

When calling the program from the proxy i get error message: Screen output without connection to user.

The program looks like this:

SUBMIT RPRCCC00 AND RETURN

WITH BEL_CLUS = 'X' "

WITH BEL_EINF = ''

WITH BEL_NONE = ''

WITH FILE_IN = filepath

WITH FIRMENNR = company

WITH NOT_LOKL = 'X'.

When I Call the proxy in foreground i get a list with errors and warnings, I suspect that it is this list, that is the problem. Can I suppress the list, or get the information to a internal table.

Kind regards

Mikkel
