You use master locks to ensure that complex planning sequences do not terminate because of lock conflicts with other users. On the Master Locks tab, you can display and delete active master locks.

Master locks are set at runtime by planning sequences at InfoCube level and linked to the process chains as steps. Before processing the data, the system determines all required selections. The system first tries to set a normal lock for these selections. If this is possible, these selections are saved as master locks and the normal locks are removed. After this, no users can change data in this area.

The process chain itself normally runs in the background. Individual subprocesses can be authenticated as master locks and only these are permitted to pass the master lock. When the planning sequences are run, the data to be edited is protected as usual by normal locks. Once the process chain has processed the data, the master locks are removed.

Integration

Master locks are only set by planning sequences in process chains.

Features

Table Master Locks: Header Entries

The master locks set by a process chain are assigned a lock handle. The system displays the header entries for each locked selection (Lock Handle, InfoCube, Process Chain, Process Variant).

Table Lock Records

The system displays the locked selections for the lock handle. The display is grouped by header entries (Lock Handle), the associated selections (Number of Selection Table), the Characteristic, the interval type (Interval) and the lower and upper interval boundaries of the selection (Internal Characteristic Value). The selections themselves are normally displayed in the lock table: For each characteristic, each selection is a disjunctive union of open, half open and closed intervals.

The type of interval can be:

  • ( ) for an open interval

  • [ ) or ( ] for a half open interval

  • [ ] for a closed interval

Activities

  1. Select an InfoProvider. The system detects all master locks from the real time-enabled InfoCubes or aggregation levels and displays them in the overview.

  2. To delete a master lock, delete the corresponding row in the Master Locks: Header Entries table.

    Note Note

    Even if you delete master locks, the transaction data is protected at runtime by normal active locks. Without the master lock, it might not be possible to execute parts of planning sequences due to lock conflicts with other users.

    End of the note.
