Hi Ian
Following on from my previous response...
This is the table link but am sure you can get this via FM as well, here goes:
GUID of REVIEW links to GUID1 of /RPM/RELATION_D
Note relation types RRN (Initiative) and RRI (Item). Get the GUID 2 value for each of the relation types
The GUID 2 value for RRI (Item) links to the PORTFL_ITEM_GUID in table /rpm/item/d. Filter where VERSION_ITEM = '' to get the current Item or 'X'to get the versions, or leave blank to get everything
The GUID 2 value for RRN (Initiative) links to INITIATIVE_GUID in table /rpm/item_d AND to GUID of table INM_INITIATIVE
There will be an easier way I am sure to get this via FM but just wanted to provide you with the table relationship as per your request
