  The SAP error message /SAPAPO/OM_ERROR2120 indicates that there is an attempt to create an inactive planning version while trying to update the Available-to-Promise (ATP) time series.

  Review Configuration: Check the configuration settings related to planning versions and ATP to ensure that they align with your business processes and requirements.
