deletePartyRelationship removes record and not set thruDate

[Anil Patel]

Hi,
deletePartyRelationship service defined in PartyServices.xml file  
between line 806 and 812 removes record from database.  
PartyRelationship entity has thruDate. When entity has such field I  
expect to expire record instead of removing it.

Like in case of SFA, We create a Lead and then later a Lead is  
converted to Account. In lead conversion process I'll like to expire  
old PartyRelationship (of type LEAD_OWNER) and create new relationship  
of type ACCOUNT. This will preserve history.

I am wondering if its ok to change implementation of  
deletePartyRelationship method. If no body has any objections I'll  
modify it to set thruDate instead of removing record.

Regards
Anil Patel
