Check/Simulation (SAP Library - Work Clearance Management (PM-WCM))

Check/Simulation

Use

You can use checks to ensure that lockout/tagout can be processed safely and free of conflict. The checks run automatically. Some checks are mandatory, some are optional. You can deactivate optional checks in Customizing.

We distinguish between general checks and dedicated checks. The general checks run during every operational step; the dedicated checks only run for certain operational steps.

Features

The system uses the general checks to check, among other things, whether:

An authorization is available

Switching is blocked by an approval.

The operational step is valid

Switching is blocked by an operational protection

In addition, there are also the following dedicated checks:

Tagged and/or untagged

Completeness and correctness

Test cycle

Untagging

Time frame

Reference object

Conflict

You can also execute the dedicated checks as a simulation:

On the maintenance screen of the WCM object you can simulate whether the items can be completely tagged or untagged.

On the switching screen of the Operational WCD you can simulate what would happen if you tag or (temporarily) untag the selected items. In this case, the system simulates the checks that would be executed subject to the respective planned status.

If you set the status PREP (Prepared), the system automatically executes the check "Tagged and/or untagged":

All other dedicated checks occur with the following statuses:

Check/Simulation	Status BTG (Tag)	Status BTUG (Untag temporarily)	Status BUG (Untag)
Completeness and correctness		X	X
Test cycle		X
Untagging			X
Time frame	X	X	X
Reference object	X
Conflict	X	X	X

The graphic shows the order in which the dedicated checks and simulations are executed.
