Root data segment definitions

The root data segment contains information used to load the UMF input document.

Tag Name Type Required Explanation
DSRC_CODE Char(25) Yes A short description of the data source.
DSRC_ACTION Char(1) Yes The source system action that caused the record to be sent. Valid values are:
A
Indicates that this is a new account that has been added.
C
Indicates that this is a change to an existing account.
D
Indicates that all data for this account should be soft deleted.
Note: Using a DSRC_ACTION value of D has a negative performance impact. This is because not only does the data have to be deleted, but the re-resolve process against the data must also occur.
Note: If using a DSRC_ACTION value of D with unresolve not enabled, incorrect future resolution may occur if the entity (DSRC_ACCT) is re-added with different information. The preferred solution is to use a DSRC_ACTION value of D with unresolve enabled. If that is not possible, then you should use a DSRC_ACTION value of F.
F
Indicates that all data for this account should be hard deleted.
Note: Using a DSRC_ACTION value of F will cause all data associated with the identity to be permanently deleted.
DSRC_ACCT Char(25) Yes The unique ID for the entity in the data source in the system. This must be chosen and mapped carefully. This value is used to indicate records that are known to belong to the same account; records with the same value for DSRC_ACCT are treated as the same identity and will always be consolidated together in the repository. If there is no identifier in the source system that can be trusted for this purpose, specify a unique ID for each record from the source system, to prevent unrelated records from being incorrectly resolved.
DSRC_REF Char(40) Yes A user-defined field to aid in tracing repository data back to source system records. In database terms, this field can be used as a foreign key to source system records. This value is not used in entity resolution, but it is often useful to specify a locator to the record in the source system, especially in situations where the DSRC_ACCT alone cannot be used to pinpoint the exact record in the source system. In cases where DSRC_ACCT can pinpoint the record, specify DSRC_REF with the same value for DSRC_REF as DSRC_ACCT.
SRC_CREATE_DT Datetime No The date this record was created in the source system.
SRC_LSTUPD_DT Datetime No The date this record was last updated in the source system.
SRC_LSTUPD_US Char(15) No The source system's last update user code or ID.
NUM_MERGED Integer Yes if a UMF_MERGE document Count of forced resolution merge segments within the document.
MERGE_TYPE Char(50) Yes if a UMF_MERGE document Describes the intent of the UMF_MERGE input document. Valid values are: FORCE_RES
UNDO   Yes if a UMF_MERGE document Used for reverting previously forced resolutions. This tag will remove the specified account's forced resolve ID.Valid values are:
  • 0 - Do nothing.
  • 1 - Revert previosuly forced resolution.
DESCRIPTION     Description of a disclosed relationship.
LOAD_GROUP     Load group of a disclosed relationship.
