We want to filter out the empty messages rather than letting it go into the error queue.
In the filter node we checked for

Root.Body IS NULL,

Root.MQMD.Format = ''

and we also tried

Root.Body.Blob IS NULL .....

nothing works out all the messages goes to error queue.

Any suggestions?

LENGTH(BITSTREAM(InputBody)) = 0

You put

Code:

Root.Body IS NULL
Root.Body.Blob = ''

check your syntax i.e Root.XML or Root."BLOB"."BLOB" or Body."BLOB" or Body. not Root.Body

I haven't tried it but my guess is that you would still get the body of the message parsed into the messsage tree (i.e not null) but with no content

I wouldn't have though it would work in the XML domain as it is not well formed XML but would need input node to be in BLOB domain

So how about

Code:

Root.XML.Body = '' (if <Body> is high level tag)
Root."BLOB"."BLOB" = ''
InputBody."BLOB" = ''

worth tracing to see what the filter statement is evaluating
