Informational message

How to fix this error?

Block tasks only when they in a blockable state.
Tasks that do not require manual interaction (that is, tasks other than
data entry and manual posting) are in a blockable state when their
status is one of the following:
Without Errors
Without Errors but with Warnings
Unblocked
Pending Completion of Preceding Task
Manual tasks are the exception because these are blockable regardless of
the current task status.
Furthermore, all tasks that precede a given task must be blocked before
the given task itself can be blocked. This applies to all tasks.

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