I am sorry, After creating the company, if you need to modify the financial year start date and end date in BUSY, you might face limitations. To resolve this problem, you may need to follow these steps:
Step 1: Create a new company.
Step 2: While creating a company, specify the correct financial year.
Step 3: Use the "Copy Master, Users, and Configuration" settings to copy masters from the old company to the newly created company.
Step 4: Otherwise, follow the XML export and import technique to import the master and transaction data from the old company to the new company.
