OMB02904 Namespace Conflict Creating Mapping

Question

Hi, we are running OWB 11GR2 on Windows and I am having trouble creating a mapping as allegedly it already exists. I can find no trace of this either through the GUI, through OMBPlus, or even using the JAVA APIs to find the offending mapping. It is also not visible in owbsys.all_iv_xform_maps or owbsys.all_iv_objects.
I cannot OMBDROP the mapping as it does not exist !
The full message in OMBPLUS is OMB02904 Namespace Conflict for map name WORK_SELF_EMPLOYED_INCOM_TA1M1: API0408 Within same namespace domain one object has already used the name WORK_SELF_EMPLOYED_INCOM_TA1M1
If you have any suggestions they would be gratefully received !
Phil

Answer 1

Our repository DB uses a Windows character set WE8MSWIN1252.
I have done a trawl through mappings and tables through all our Modules in a couple of ways (note my OMBPlus may not be the best you have ever seen). Note that these code snippets do work with 'real' mappings, but they do not find my phantom mapping.
set objectToFind WORK_SELF_EMPLOYED_INCOM.*
OMBCC '/IDP'
set moduleList [OMBLIST MODULES]
#set moduleList [list IPS2_SA1]
foreach moduleName $moduleList {
puts "Module name = $moduleName"
OMBCC '/IDP/$moduleName'
set tableList [OMBLIST TABLES '$objectToFind']
foreach tableName $tableList {
puts "=== Found table $moduleName/$tableName"
set mapList [OMBLIST MAPPINGS '$objectToFind']
foreach mapName $mapList {
puts "=== Found mapping $moduleName/$mapName"
============================================
Java API based search
set mapToFind WORK_SELF_EMPLOYED_INCOM_TA1M1
set repManager [java::call oracle.owb.connection.RepositoryManager getInstance]
set owbConnection [$repManager getConnection]
set projectManager [java::call oracle.owb.project.ProjectManager getInstance]
set project [$projectManager getWorkingProject]
# for every module
set modList [$project getOracleModuleNames]
set modCnt [$modList length]
for {set ic1 0} {$ic1 < $modCnt} {incr ic1} {
# Find your Oracle module
set modName [$modList get $ic1]
set modObj [$project findOracleModule $modName]
if {("$modName" != "RELEASES") && ("$modName" != "ARCHIVE")} {
# Proc logit defined earlier to output to a file
logit "Processing module $projName/$modName"
set mapList [$modObj getMapNames ]
set mapCnt [$mapList length]
for {set ic2 0} {$ic2 < $mapCnt} {incr ic2} {
set mapName [$mapList get $ic2]
if { "$mapName" == "$mapToFind" } {
logit "======= Found the bugger $mapName"
===============================
Nothing here either ....
