  The SAP error message /SAPAPO/OM_SYNC320 indicates a discrepancy between the data stored in the LiveCache and the data in the database for a specific quantity. This error typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is a synchronization issue between the LiveCache (which is used for real-time data processing) and the underlying database.
  Cause:
