Rather urgent CPYTOSTMF problem

Hello Chaps and Chapesses

We have an urgent problem here, we have to send messages out to clients to 
inform them when when cargo arrives, this has been working up until recently. 
The messages actually stopped around the same time we installed WDSC. (I cannot 
believe that this was the cause, but maybe some of you know better)

Anyway the problem we are getting is when we try to do the CPYTOSTMF, the path 
is set up in the program as follows:

                                                               
       CHGVAR     VAR(&PATH) VALUE('QSYS.lib/' *TCAT &LIB +    
                    *TCAT '.lib/' *TCAT &OBJ *TCAT '.file/' +  
                    *TCAT 'SND.mbr')                           
                                                               
       CPYTOSTMF  FROMMBR(&PATH) TOSTMF(&FILENAME) +           
                    STMFOPT(*REPLACE) STMFCODPAG(*PCASCII) +   
                    ENDLINFMT(*FIXED)                          

 the program falls over with this:

     Object not a QSYS.LIB object.  Object is                          
       /home/AGCSYSBH/QSYS.lib/AGCFTPOUT.lib/F001407322.file/SND.mbr.  
     Object not copied.  Object is                                     
       QSYS.lib/AGCFTPOUT.lib/F001407322.file/SND.mbr.                 

We cannot work out where the /home/AGCSYSBH comes from (AGCSYSBH is the user 
profile that submits the job, which runs all day waiting for message).

Is the message telling us that the file is in the /home etc. directory or that 
the path is wrong? The messages are deleted so we are not sure where they were 
if they got there at all.

Another problem is that 3rd party software sets up the message to be sent, but 
this has not changed for ages. 

TIA
