Your process is correct but with one small detail missing. The product
identifier in the above example is "/io/ldm/data/nws/LF.TXT" so your
pqact entries must be expecting that identifier.  Do you have an
pqact entry for that identifier under feedtype IDS? Another problem is
that pqsurf is looking for the standard WMO identifier too. ie "SAFR31
LFPW 311230" Actually pqinsert should have an id flag to set the
identifier. One solution would be to create a filename with the desired
WMO indentifier and then use pqinsert.  The other problem about the
product already being in the que is that the LDM sees it as a duplicate
product and so it ignores it. One can wait unitl the product is removed
from the que, about an hour on a LDM receiving data or create a product
that is slighty different.  The product is considered the same from the
WMO heading down to the end of the data. One quick way to change the
product would be to duplicate a internal report.
