Data Freeze Information

Data preparations start during the build phase and continue throughout the project. Both HCM and Finance project teams are busy working to minimize the downtime to migrate from the current SAP system to the newly transformed SuccessFactors at the end of December and SAP S/4 HANA at the end of June 2018.  In order to efficiently minimize the volume of data to be converted and validated, the teams need additional assistance from the Purdue community.

  1. Close any old open transactions.
  2. Analyze the duration of the normal life cycle of a transaction to determine a data entry freeze date.
  3. Address any issues that are causing delays in a transaction’s life cycle.
  4. Enforce data entry freeze dates to reduce the number of open transactions to convert during the migration period.
