What causes this issue?

Under Project Parameters, you can specify settings for specific
activities. These settings can then be used during your project. If
these settings are not set to final (flag Final), then you can change
these settings when you execute the activity in the process tree.
However, if these settings are set to final, then the predefined
settings cannot be changed when you execute the relevant activity in the
process tree.

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

For the activity User Lock Settings for Receiver System, predefined
settings exist that cannot be changed (flag Final is set under Project
Parameters). To confirm these settings and proceed to the next activity,
choose the pushbutton Execute and Close.
