Q : OMBPLUS, find TARGET TABLE

Question

With OMBRETRIEVE and HAS CONNECTION you can find out it the table is an target table, however this statement doesn't work from a JOIN OPERATOR
statement:
OMBRETRIEVE MAPPING 'COM_ODS_ODS_BGT' HAS CONNECTION \
FROM GROUP 'OUTGRP1' OF OPERATOR 'JOIN' \
TO GROUP 'INOUTGRP1' OF OPERATOR 'COM_ODS_BUDGET'
How can this be achieved? and does it work for the other
operators ?

Hi Dirk-Jan,
you can use the tcl proc as listed below. It returns a list of respectively mapping sources or targets of types TABLE of VIEW.
syntax:     ::xos_omb_add-on::xOMBRETRIEVE [fco_type] [fco_name] [optionClause]
fco_type:          MAPPING
fco_name:          <MAPPING_NAME>
optionClause:     SOURCES | TARGETS
Cheers!

namespace eval ::xos_omb_add-on {
# This procedure returns a list of respectively all sources or targets of a
# given mapping.
# @param     fco_type          in     string     The type of the component. Valid values:
#                                                  MAPPING
# @param     fco_name          in     string     The physical name of the component in
