SAP Error Message - Details

• Message type: E = Error

• Message class: SO - SAPoffice: message texts

• Message number: 198

• Message text: <&> is being processed by &

What causes this issue?

The object you wish to process is currently locked either by yourself
or by another user.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

To avoid inconsistent changes, the system only allows one user to make
changes to an object at a time.

How to fix this error?

You can currently only carry out the desired function in display mode
and make the changes at a later date.
If you are the user locking the object, check whether you are
processing it in another session.
If this is not the case, then the internal system lock was not reset,
for example, after a system crash.
In this case, the lock has to be reset manually.
To do this, select Tools -> Administration -> Monitor -> Lock entries.
If you do not have authorization for this, please contact your system
administrator.
