'' Example where the first DEF has Combine instead of New + the DEF template had 2 multiple items''

==Case Combine==__NOEDITSECTION__
The solution is actually '''not''' to add rows to the table ''link'' but to update some columns of existing rows.
<ol><li>''approval_state'' should be NEW_LOCATION or NEW depending on item<li>''to_guid'' should be to the Location GUID<li>''to_link_type'' should be LOCATION<li>''system_link'' should be NULL<li>''to_link_is_version'' verify that it is '''f'''<li>''update_type'' should be NULL</ol>
