TCA value set error

Question

I have created three value sets and this one is to extract the contact from the id the value set gets sent.
SELECT PARTY.PARTY_NAME, DECODE(ACCT_ROLE.STATUS,'A','Active','I','Inactive')||' '||PARTY.PERSON_LAST_NAME||' '||PARTY.PERSON_FIRST_NAME,
ACCT_ROLE.CUST_ACCOUNT_ROLE_ID
FROM HZ_CUST_ACCOUNT_ROLES ACCT_ROLE, HZ_PARTIES PARTY, HZ_RELATIONSHIPS REL
WHERE 1=1
AND ACCT_ROLE.PARTY_ID = REL.PARTY_ID
AND ACCT_ROLE.ROLE_TYPE = 'CONTACT'
AND REL.SUBJECT_ID = PARTY.PARTY_ID
AND PARTY.PARTY_TYPE = 'PERSON'
AND :$FLEX$MISAR_HZ_PARTIES = ACCT_ROLE.CUST_ACCOUNT_ID(+)
ORDER BY PARTY.STATUS,PARTY.PERSON_LAST_NAME||','||PARTY.PERSON_FIRST_NAME
When I reference the value set through a standard custom form through a descriptive flexfield I get the following error message:
APP-FND-01242: Cannot read value from field $FLEX$MISAR_HZ_PARTIES
Cause: The field $FLEX$MISAR_HZ_PARTIES could not be located or read.
Action: This error is normally the result of an incorrectly-entered field name string in a trigger, or a field string that does not uniquely specify a field in your form. Correct your trigger logic to precisely specify a valid field.
I've checked all the other value sets by running the SQL through SQL*Plus and they work fine.
There is no id to send to this value set but it shouldn't fail.
Any ideas why this error is coming up?

Answer 1

The issue is usually caused by descriptive flexfield validation logic referencing a <block_name>.<field_name> combination that does not exist in the form.
The setup causes the issue because the flexfield is unable to pass validation. Either disable the problematic descriptive flexfield or remove all references in the descriptive flexfield validation logic to the invalid <block_name>.<field_name> combination.
Solution
-- To disable the descriptive flexfield, please execute the following steps::
1. Go into the System Administrator responsibility
2. Navigate to Application > Flexfields > Discrete
3. Query for the problematic descriptive flexfield. See Note 1016241.102, for guidance in identifying the flexfield.
4. Clear the 'Freeze Flexfield Definition'Note 1016241.102, for guidance in identifying the flexfield.
4. Clear the 'Freeze Flexfield Definition' checkbox.
5. Disable any Global Data Element segments.
6. Disable any context-sensitive (non-global) structures.
7. Check the 'Freeze Flexfield Definition' checkbox.
8. Save the changes.
9. Retest the issue.
10. Migrate the solution as appropriate to other environments.
