I search the Jira but asking here in case I missed something.
when a complete entity export is done.The dependent entities are not sorted so
they are import after the parent Id are. I am not sure at this point if it is
entity specific.
example
<PartyType partyTypeId="Fullfilment" parentTypeId="Suppliers"
lastUpdatedStamp="2006-06-18 02:50:03.697" lastUpdatedTxStamp="2006-06-18
02:50:03.587" createdStamp="2006-04-10 14:21:32.027" createdTxStamp="2006-04-10
14:21:32.027"/>
is before
<PartyType partyTypeId="Suppliers" hasTable="Y"
lastUpdatedStamp="2006-06-18 02:50:03.737" lastUpdatedTxStamp="2006-06-18
02:50:03.587" createdStamp="2006-04-10 14:19:13.297" createdTxStamp="2006-04-10
14:19:13.297"/>
so when it imports, there is a error and and the import for the file is rolled
back
