List Joins of all Folders

Question

Hi!
Within my Business Area I have several Folders which have joins defined amongst each other.
I would like to list those joins, eg. KEY_NAME, KEY_DESCRIPTION, what kind of join and most importantly the exact join formula like for example MYSCHEMA.TABLE_A.PK_A_ID = MYSCHEMA.TABLE_B.FK_A_ID.
How can I do this by querying the EUL5-tables? I already saw that EUL5_KEY_CONS is part of this, but can't figure out how to get what I need.
Any idea is very much appreciated!
Cheers

thanks!
i tweaked it a little and finally got this:
SELECT
KEYS.KEY_NAME Join_Name,
KEYS.key_description Join_Desc,
x1.ba as "Master_Business_Area",
MST_FOLD.OBJ_NAME Master_Folder,
MST_ITEM.EXP_NAME Master_Item,
x1.col as "Master_Column",
x2.ba as "Detail_Business_Area",
DTL_FOLD.OBJ_NAME Detail_Folder,
DTL_ITEM.EXP_NAME Detail_Item,
x2.col as "Detail_Column",
decode(KEYS.fk_one_to_one,0,'One to Many',1,'One to One','None') RelationShip
,decode(KEYS.fk_mstr_no_detail,0,'Equi Join',1,'Outer Join','None') JoinToDetail
,decode(KEYS.fk_dtl_no_master,0,'No',1,'Yes','None') OuterJoinOnMaster
,decode(KEYS.fk_mandatory,0,'No',1,'Yes','None') MasterMustExist
FROM
EUL5_KEY_CONS KEYS,
EUL5_EXPRESSIONS JOIN_LINK,
EUL5_EXPRESSIONS MST_ITEM,
EUL5_EXPRESSIONS DTL_ITEM,
EUL5_OBJS MST_FOLD,
EUL5_OBJS DTL_FOLD,
(SELECT
bas.ba_name as ba,
obj.obj_name as f,
CASE WHEN obj.obj_ext_owner IS NOT NULL
THEN obj.obj_ext_owner || '.' || obj.sobj_ext_table
ELSE NULL
END as "Table",
ex.it_heading as "Element",
CASE

obj.obj_id = ex.it_obj_id) x1,
(SELECT

AND
bal.bol_obj_id = obj.obj_id
AND
obj.obj_id = ex.it_obj_id) x2
WHERE
JOIN_LINK.JP_KEY_ID = KEYS.KEY_ID
and JOIN_LINK.EXP_TYPE = 'JP'
and MST_ITEM.exp_id =
TO_NUMBER(SUBSTR(JOIN_LINK.EXP_FORMULA1,INSTR(JOIN_LINK.EXP_FORMULA1,'6,')+2,(INSTR(JOIN_LINK.EXP_FORMULA1,'],') - (INSTR(JOIN_LINK.EXP_FORMULA1,'6,')+2))))
and DTL_ITEM.exp_id =
TO_NUMBER(SUBSTR(JOIN_LINK.EXP_FORMULA1,INSTR(JOIN_LINK.EXP_FORMULA1,',[6')+4,(INSTR(JOIN_LINK.EXP_FORMULA1,'])') - (INSTR(JOIN_LINK.EXP_FORMULA1,',[6')+4))))
and MST_ITEM.IT_OBJ_ID = MST_FOLD.OBJ_ID
and DTL_ITEM.IT_OBJ_ID = DTL_FOLD.OBJ_ID
and MST_ITEM.exp_id = x1.exp_id (+)
and DTL_ITEM.exp_id = x2.exp_id (+)
order by
x1.ba ,
MST_FOLD.OBJ_NAME ,
MST_ITEM.EXP_NAME ,
x1.col ,
x2.ba,
DTL_FOLD.OBJ_NAME ,
DTL_ITEM.EXP_NAME ,
x2.col;
Here I have also the real table name, but somehow there are some joins where I have a MST_ITEM.EXP_NAME Master_Item but no x1.col as "Master_Column" (and same for details). What could this be? A join pointing to a folder item which no longer exists (or event the whole folder is gone?)?
