Error when calling program RSPROCESS

Hi to all,

I have created a JOB to trigger a chain in my BIW and right after the start I get the following message:

10.07.2014 11:49:54 CALL_INVALID: Can not create MESSAGE_CONTAINER MTE  [4YHIYF3SDA56JH2C8A8OIPR3X 07/10 11:49:54] under     RSAR          051          S

The chain, of course, doesn't start. I have created the job with my user but I changed the step user to ALEREMOTE and I still get this message

Do you have any idea of which is my problem here?

Thanks

Regards

Miriam
