Posting only possible in periods &1 and &2 in company code &3

What causes this issue?

The posting date entered is not within one of the permitted posting
periods (current period/previous period).
This can be due to one of two reasons:
The correct current period has not been set in the system.
For the system, the first of the entered periods is the current period.
At the beginning of a new period, your systems administrator must
change the current period in the material master record, using the
function "Shift periods". This has not yet been done.

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

You have entered a wrong date in the field "Posting date".

How to fix this error?

Check the posting date and correct it if necessary. If your input is
correct, inform your systems administrator that the "period shifting"
(period-end closing) process has not yet been completed. <ZV>Copied
