Issue/Introduction

Your Load Data Warehouse (DWH) job is failing on a custom lookup, could be with one of the errors below:

ORA-00904: invalid identifier 
ORA-30926: unable to get a stable set of rows in the source tables
ORA-01427: single-row subquery returns more than one row

 The lookup might not be having a proper query to work with DWH, how can I find out which attribute  and object it is on, to disable the lookup from DWH?

Environment

Release: All Supported Releases
Component: Clarity Data Warehouse

Resolution

How to find out the attribute / object affected for the custom lookup:

  1. Check the error message in Home - Job - Log or in bg-dwh.log
  2. Take the lookup table name
    • For example here is a part of the error:

ERROR: THERE WERE ERRORS DURING LOOKUP JOB EXECUTION FOR THE TABLE - DWH_LKP_TEST_VAL_00

Lookup table is DWH_LKP_ TEST_VAL _00

     3. Remove the DWH_LKP_ and the _00 if present. You need the lookup name only.

     4. Modify the query below to include the corrected value

    • Example for TEST_VAL:

select object_name as Object_id, column_name as Attribute_code, lookup_type as Lookup_id
from (
select clt.id, clov.id, oca.id,
  clt.lookup_type, clt.source,
  clov.sql_text_id, clov.object_code,
  oca.object_name, oca.internal_name, oca.column_name, oca.data_type,
  oca.partition_code, oca.is_multivalued, oca.default_value, oca.derived_object_code,oca.internal_name
from cmn_lookup_types clt
join cmn_list_of_values clov
on clt.lookup_type = clov.lookup_type_code
and clov.is_system = 0
join odf_custom_attributes oca
on oca.lookup_type = clt.lookup_type
and clt.lookup_type like '%TEST_VAL%'
)
group by object_name, column_name, lookup_type
order by object_name, lookup_type
 
Note: It has to include the % at the end as sometimes not the full lookup name is used in the table name.

    5.The query will give you the exact object name and attribute that has to be unchecked from Data Warehouse. Connect to Administration - Objects - <object> - Attributes - Select and Uncheck it.
    6. Run Load Data Warehouse - Full Load

    7. Then run Load DWH - Incremental Load

This should fix the issue.
