Wrong year definition - can it be solved - 3.56A

I have a problem, while I have closed a financial year 1-1-02/31-12-02 and it should have been 1-5-01/30-4-02 - can I do anything to solve the problem ??. It was the periods, which have been incorrectly set, are there any way to solve the problem

If you have an AL license, you can edit the fields of table no. 50 to allow editing. Otherwise drop me a mail, and I will send the object to you (danish version?) pr@navigroup.dk

If you don’t have the AL license, you can create a report tha deletes all the records in table 50 (Periode). Then create the periods again.
