Parse program which is having table definition

Hi,

i am using a program to parse a 4GL progress code, it works fine when there is no table definition is used but fails if i use a table refrence, gives me below error -

---------------------------
Error (Press HELP to view stack trace)
---------------------------
org.prorefactor.refactor.RefactorException: testparse_table.p:1: Unknown table name: customer
---------------------------
OK Help
---------------------------

i am having sports database connected on editor. below is the code i am using to parse and my pf file is using sports db -

using org.prorefactor.refactor.* from assembly.
using org.prorefactor.treeparser.* from assembly.
using org.prorefactor.core.* from assembly.
using java.io.* from assembly.

def var filename as char init "testparse_table.p".
def var indent as int no-undo.

def var outed as char view-as editor large scrollbar-vertical size 78 by 22.
display outed with frame f1 no-box no-labels.

def var prsession as class org.prorefactor.refactor.RefactorSession.

prsession = org.prorefactor.refactor.RefactorSession:getInstance().

def var javafile as class java.io.File.
javafile = new java.io.File(filename).
if (not javafile:exists()) then do:
message "Could not find file: " + fileName view-as alert-box.
return.
end.
def var pu as class org.prorefactor.treeparser.ParseUnit.
pu = new ParseUnit(javafile).
pu:treeParser01().

run walker(pu:getTopNode()).
enable outed with frame f1.
wait-for "endkey" of default-window.

procedure walker:
def input param node as class JPNode.
if (node eq ?) then
return.
outed:insert-string(fill(" ", indent) + node:ToString() + "~r~n") in frame f1.
indent = indent + 1.
run walker(node:firstChild()).
indent = indent - 1.
run walker(node:nextSibling()).
end procedure.

Any idea, why i am getting this error, am i missing some configuration?

Regards,
Ganesh
