I've been using MessageSubfiles many times and so fat I have not had
any problems until today....

I'm Calling srvpgm B from PGM A. In this SrvPgm B I have procedure
WriteToMSGF which writes to message subfile using SNDPGMMSG:

if ErrorHappened;
%subst(msgf:1:8) = 'MSGFILEID';
msgid = 'MSGID';
pgmq = 'WRITETOMSGF';
%subst(msgq:1:7) = '*TOPGMQ';
msgdta = '';
Pgm_SNDSFMSG(msgf : msgid : pgmq : msgq : msgdta);
ENDIF;

Thing is I don't see those messages on my screen and srvpgm B has its
own Display File.
In job log I can see all messages properly and by using F1 on one of
them I can see this:

From program . . . . . . . . . : SNDMSG
From library . . . . . . . . : LANSAFD4
From module . . . . . . . . : SNDMSG
From procedure . . . . . . . : SNDMSG
From statement . . . . . . . : 1900

To program . . . . . . . . . . : PROGRAM1
To library . . . . . . . . . : LANSAFD4
To module . . . . . . . . . : PROGRAM1
To procedure . . . . . . . . : WRITETOMSGF
To statement . . . . . . . . : 79200

PROGRAM1 is name of program which calls my SRVPGM. SNDMSG is name of
CL program which run SNDPGMSG command. Do I have this problem because
srvpgm's don't have their own message queue? How I can solve this
problem? Should I switch to using some API? Please help :(

The service program, itself, doesn't have a message queue but each
service procedure that is called within the service program has its own
message queue. So, I notice that you are specifying a destination message
queue name in the API. This same message queue name would have to be
referenced by your message subfile in order for the message to be seen. Is
this the case?
