EBS_SITE_DEST_KEY in Demantra Staging Table

 Hi,

We do have duplicate values for EBS_SITE_DEST_KEY (as we can have in EBS same shipto attached to multiple orgs).
Due to that reason when we run EP_CHECK_ITEMS/LOCATIONS it is dumping those records into the error table.
Is there any work around  for loading the below records or  am I missing something here. Below is the sample data.
Error in T_SRC_LOC_TMPL is 'Duplicate attribute value - ebs_site_dest_key'.   We are using custom collections.


Org      Shipto        EBS_SITE_DEST_KEY
1            11                     1234
2            11                     1234
3            11                     1234


Thanks!
