Hi Prabhu,
I donu2019t recall all the details, but after researching this before I came to the conclusion that the XI Value Mapping cache should only be used as a cache and not used as the master where item level maintenance is performed.  I believe it mainly involved the fact that there is no Update operation.  You need to delete first then re-create.  However, itu2019s easy to introduce duplicate items if you donu2019t use all the right values for the delete.
So, I added the DeleteContext operation as the first item in the ValueMappingReplication  xml.  In this way the entire Context is deleted and re-created every time.  We can then be sure the cache is always in-sync with our source, which we maintain in Excel.
<?xml version="1.0" encoding="utf-8"?>
<ns:ValueMappingReplication xmlns:ns="http://sap.com/xi/XI/System">
  <Item>
    <Operation>DeleteContext</Operation>
    <Context>urn:company-com:valuemap:test</Context>
  </Item>
  <Item>
    <Operation>Insert</Operation>
    <GroupID>c7941e905e9711dfc8c5001a4b0631cb</GroupID>
    <Context>urn:company-com:valuemap:test</Context>
    <Identifier scheme="Alpha" agency="Alpha">A</Identifier>
  </Item>
