Hard Delete Detection Table

Hard Delete Detection Table

The hard delete detection table is a repository table that you create to store metadata that the
MDM Hub
 requires to detect hard deletes in source systems. The name of the hard delete detection table is C_REPOS_EXT_HARD_DEL_DETECT.
The following table describes the columns of the hard delete detection table:
Column Name
Datatype and Size in Bytes
Description
ROWID_TABLE
CHAR (14)
Contains values of the ROWID_OBJECT column of the staging table for which hard deleted records need to be detected. The ROWID_TABLE column cannot have a null value.
HDD_ENABLED
INTEGER
Enables or disables the
MDM Hub
 to detect hard deletes for a staging table. The HDD_ENABLED column cannot have a null value.
Use one of the following values:
  • 0. Enables the
    MDM Hub
     to detect hard deletes.
  • 1. Disables the
    MDM Hub
     to detect hard deletes.
Default is 0.
HDD_TYPE
VARCHAR2 (14)
Indicates the type of hard delete for the staging table.
Use one of the following values for the hard delete type:
  • DIRECT. Performs the direct hard delete of the base object record.
  • CONSENSUS. Performs the consensus based hard delete of the base object record.
DELETE_FLAG_ COLUMN_NAME
VARCHAR2 (30)
Name of the staging table column that contains the value of the delete flag for any hard-deleted records that the
MDM Hub
 detects.
DELETE_FLAG_VAL_ ACTIVE
VARCHAR2 (14)
Value of the delete flag column for active records.
DELETE_FLAG_VAL_ INACTIVE
VARCHAR2 (14)
Value of the delete flag column for inactive records.
DELETE_FLAG_VAL_ PARTIAL
VARCHAR2 (14)
Value of the delete flag column for the partial delete in a consensus delete scenario.
HAS_END_DATE
INTEGER
Indicates whether the staging table has an end date column. The HAS_END_DATE column cannot have a null value.
Use one of the following values:
  • 0. Staging table does not have an end date column.
  • 1. Staging table has an end date column.
Default is 0.
END_DATE_COLUMN_NAME
VARCHAR2 (30)
Name of the end date column.
The
MDM Hub
 uses the column when HAS_END_DATE=1.
END_DATE_VAL
DATE
Value to use for the end date.
If the implementation requires that you hard-code an end date value, then that value is stored in the END_DATE_VAL column in the MM/DD/YYYY format.
Default is SYSDATE.
TRAN_HDD_ENABLED
INTEGER
Indicates whether the process to detect hard deletes is transactional. The TRAN_HDD_ENABLED column cannot have a null value.
Use one of the following values:
  • 0. The process to detect hard delete is not transactional.
  • 1. The process to detect hard deletes is transactional and does not compare the full load against the previous landing and landing table.
Default is 0.
