How to get change only data from child data group in HCM Extract
We have a requirement to send employee's current and future assignments to the target system from Oracle HCM. It should always be in change only mode. If we take Extract Assignment ID as threading database item and PER_EXT_SEC_ASSIGNMENT_NOW_FUTURE_UE" as the user entity in the Root Data Group, it will always result in duplicate rows because of duplicate assignment IDs in the UE. To overcome this, we have used "PER_EXT_SEC_ASSIGNMENT_UE" as Root data group UE with Extract assignment ID as threading DBI. "PER_EXT_SEC_ASSIGNMENT_NOW_FUTURE_UE" is used in the Child Data group, joined by assignment ID.
