Edit form with an Inner Join - Can not update/delete data?!

Question

Hi all,
I have an Edit form which shows me data from 2 tables (through an Inner Join SQL-Statement). I just realized that I can not edit data anymore, the following error msg appears:
Error in mru internal routine: ORA-20001: no data found in tabular form
     Error     Unable to process update.
OK     
Can someone please help me?

The ringed in red are from the second table, but the first table has some more data. Here is the SQL Statement I have (D1 and D2 are from the second table - Whereas the DOBJ_NR1 and the DOBJ_NR2 are both primary keys and foreign keys in table one, but the user selects the key from table two...):
SELECT
D1.DOBJ_NR DOBJ_NR1,
D1.NAMSP NAMSP1,
D1.DOBJ_NAME DOBJ_NAME1,
D2.DOBJ_NR DOBJ_NR2,
D2.NAMSP NAMSP2,
D2.DOBJ_NAME DOBJ_NAME2,
R.RS_NAME,
R.ROLE1TO2,
R.CARDMIN1TO2,
R.CARDMAX1TO2,
R.ROLE2TO1,
R.CARDMIN2TO1,
R.CARDMAX2TO1,
R.ON_DELETE,
R.ON_UPDATE,
R.O_RS_COMMENT,
R.INS_BY REL_INS_BY
FROM
DO_RELATIONSHIP R
INNER JOIN DATAOBJECT D1 ON R.DOBJ1_NR = D1.DOBJ_NR
INNER JOIN DATAOBJECT D2 ON R.DOBJ2_NR = D2.DOBJ_NR
