10.1.2 form problem querying master details with underscore

Question

I have a problem on a form we have were by the user is querying a record and the detail block is bringing through an incorrect record. This occurs on all records that have an underscore "_"
The form is huge so i am trying to cut down whilst testing but thought i would ask the question to see if its anything obvious.
basically there are 3 tables all on there own blocks linked by the built in relationships in forms.
the user queries the top one and the other 2 are set to auto query.
the problem is with only one primary key that is referenced. This has an underscore in it.
i.e user brings in top level "1000_0"
this brings through on all detail records another primary key which is "1000-0" but the top level shows the correct "1000_0".
Is anyone aware of anything this may be, iwill endeavor to set some testing up.

Answer 1

ok i have recreated in its most basic concept and still exhibits same problem.
3 db tables.
create table testparts
(part VARCHAR2(50) PRIMARY KEY)
create table testroute
(testroutepart VARCHAR2(50),
testrouteno NUMBER,
CONSTRAINT pK_testroute_PART PRIMARY KEY (testroutepart,testrouteno)  ENABLE,
CONSTRAINT FK_testroute_PART FOREIGN KEY (testroutepart) REFERENCES testparts (part) ENABLE)
create table testroutemat
testroutepart VARCHAR2(50),
testrouteno NUMBER,
testroutemat VARCHAR2(50),
   CONSTRAINT PK_testrouteMAT PRIMARY KEY (testroutepart, testrouteno, testroutemat) ENABLE,
    CONSTRAINT FK_MP_PART FOREIGN KEY (testroutepart) REFERENCES testparts (part) ENABLE
insert into testparts(part)
values ('TEST_1');
insert into testparts(part)
values ('TEST-1');
insert into testroute (testroutepart,testrouteno)
values ('TEST-1',1);
insert into testroutemat (
testroutepart,
testrouteno,
testroutemat
values(
'TEST-1',1,'MATERIAL 1'
insert into testroutemat (
testroutepart,
testrouteno,
testroutemat
values(
'TEST-1',1,'MATERIAL 2'
commit;Then create a new form.
This form contains 4 blocks.
a non db block with one non db item on it where the user types in part.
then 3 further blocks based on the 3 tables above.
On the block for testparts this has a default where containing
part=:ctl.partand a relationship to detail block testroute
part=testroutepartset this relationship to auto query also.
Then on the blocks for testroute this has relationship to detail block testroutemat
TESTROUTE.testroutepart=TESTROUTEMAT.testroutepart and TESTROUTE.testrouteno=TESTROUTEMAT.testroutenoI then have a button on on non db block containing
go_block('TESTPARTS');
execute_query(no_validate);you then enter TEST_1 within the non db block non db item. hit button and the other items are shown i.e TEST-1 for the detail items?
Has anyone any ideas??
