X++ Code to remove the duplicate objects in AOT

Scenario : Nags came across a requirement for duplicating the production instance.He followed the following steps
1. Setup a new instance and Copied the var.aod files from production
instance and restored the DB with production DB.
2. After that he kept the application for compilation. When the
compilation ends , he tries to synchronize the Data dictionary. But
he was getting error during synchronization because some objects were
duplicated in layers. e.g System will show two ItemId fields at
table level.

Use the following code to delete the identical copy.

//Thanks for Fredshen for the following code

static void FindAndDeleteIdenticalObjects(Args _args)
SysTreeNode comparable1, comparable2;
TreeNode curLevelTreeNode, upperLevelTreeNode;
UtilIdElements utilElements, joinUtilElements;

while select UtilElements
where UtilElements.utilLevel == UtilEntryLevel::var &&
UtilElements.recordType == UtilElementType::Form ||
Utilelements.recordType == UtilElementType::Report ||
Utilelements.recordType == UtilElementType::Table ||
Utilelements.recordType == UtilElementType::Class ||
Utilelements.recordType == UtilElementType::Enum ||
Utilelements.recordType == UtilElementType::ExtendedType
//Should use join if for a normal table, but not applicable for UtilElements
//Performance hit if use exists join
select firstonly recid from joinUtilElements
where joinUtilElements.utilLevel != UtilElements.utilLevel &&
joinUtilElements.name == UtilElements.name &&
joinUtilElements.recordType == UtilElements.recordType;
if (joinUtilElements.RecId)
//Thanks for Jim Shepherd here
curLevelTreeNode = SysTreeNode::findNodeInLayer(UtilElements.recordType, UtilElements.name, UtilElements.parentId, UtilElements.utilLevel);

upperLevelTreeNode = SysTreeNode::getLayeredNode(curLevelTreenode, 1);
comparable1 = SysTreeNode::newTreeNode(curLevelTreeNode);
comparable2 = SysTreeNode::newTreeNode(upperLevelTreeNode);
if (SysCompare::silentCompare(comparable1, comparable2))
info(strFmt("Element name: %1, Element type: %2", UtilElements.name, enum2str(UtilElements.recordType)));
//Remove the node
