What happen on deleting SM12 locks?

[Former Member]

Hello,

We usually see users in SM12 who are accessing the Planning Area. I would like to know if we delete the user locks from SM12 what really happen? Does it impact liveCache consistency and anything else?

Thanks,

Hi Sanju,

Certain problems can result in locks that cannot be released again, with the result that

uses cannot access the locked objects.

These locks, however, can be deleted manually.

In general, however, you should not directly delete locks with the delete functions

offered in the lock management system. Unreleased locks are almost always the

symptom of another underlying problem. When you correct the underlying problem,

the locks will be released automatically.

First try to identify and remove the problem.

Only delete lock entries if you are sure that they are invalid and can be deleted

without impairing an active process (user session, update, and so on). Deleting a

lock held by an active user can lead to loss of the data entered by the user or to data

inconsistencies.

When a user changes data in the system, the system must then lock this data.

This prevents other users from changing the same data simultaneously and causing

data inconsistencies. This means that you can only change data in demand planning

(DP) that is not currently locked. If, for example, interactive planning is to select data

that has already been locked, then this data is automatically shown in display mode.

The liveCache lock is the most precise locking method. Using this locking method,

the system can create an entry in the lock table for multiple single values or one interval

per characteristic. The liveCache lock does not take exclusive selections into account.
