What causes this issue?

An error occurred while determining the fiscal period &V1& in period
version &V2&.

System Response

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

How to fix this error?

There are three things which could lead to this error:
The period version &V2& allocated to the company code has not been
created. In this case, you should create the period version.
The period version has been created, however the allocation of calendar
dates to the fiscal periods has not been correctly performed or in
particular with calendar-dependent period versions has not been
completely performed. Check whether the date entered &V1& for period
version &V2& has been maintained and enter the missing period.
The calendar date &V1& is invalid. This is a system error. Contact your
Systems Specialist.
