• After migrating from SAP ECC to SAP S/4HANA, issues occur in Personnel Time Management processing:

  • Time Management records beyond the go-live date (03.11.2025) are not visible.

  • Records created before migration are visible in SAP S/4HANA but cannot be processed further.

  • Creation of certain absence types is not possible.

  • Absence quotas cannot be created or updated via infotype 2006.

  • Error message displayed during absence creation or quota maintenance:
    “No entries found in table T554Y_REAC”

  • In some cases, absences are posted with the current date instead of the requested date.

  • Issue mainly occurs after transporting ECC customizing to SAP S/4HANA Quality.
