Function documentationLock Monitor for Supply Network Planning (SNP) and Demand Planning (DP) Locate this document in the navigation structure

 

You use this report to collect locks and locking conflicts in a database table, from which you can create application logs. The lock monitor analyzes the reason and details of locking conflicts and checks the lock behavior of programs.

Display the application logs to view and analyze the following types of locks:

  • Planning object SAP liveCache lock (for the system to use the SAP liveCache lock, you must activate the SAP liveCache lock in planning area administration)

    For more information about the SAP liveCache lock, see Locking in Demand Planning.

  • Administration lock (locks of SNP and DP administration tools, such as consistency check of the time series network, check of the SAP liveCache time series data, and so on.)

  • Locks on table /SAPAPO/TSQUEUE (SNP master data update)
