Your company got aquired by a company with a deferred calendar year? Usually this is the time, when you might need to think of changing the fiscal year variant.

You search in the help and get the following article: As suggested you raise a ticket and ask for support and it will be closed immediately, because your company does not use company defined fiscal year variants, but “10-Calendar Year Equals Fiscal Year”.

What other option do you have now?

During the last years I was contacted by different projects for support. After trying out various approaches I believe that setting up a new company with the new fiscal year variant is the best of all. And somehow the company is a new company. They have not only to use a different fiscal year variant, but maybe also a subsequent set of books (company set of books?). They maybe now belong to a tax group. They have different processes etc.

What would be the necessary steps to achieve this:

  1. Request a new test tenant
  2. Create a new company in the new tenant in parallel to the old company
    Advantage: master data can be re-used, at least the company independent part;
    historical data are still available
  3. Create the new Set of Books
    Fiscal year variant is a key field for the Set of Books definition, that why it cannot be changed.
    The Chart of Accounts, etc. can be reused.
  4. Assign the new company to the new Set of Books
    You cannot assign a subsequent Set of Books to a company after the first posting.
    But even if it would be technically okay, after my evaluations I do not think, it is a good approach for a new fiscal year variant.
  5. Extract all open transactions and migrate them to the new Set of Books
    Similar to a standard migration, you need to migrate open items. For open POs and SO you need to check if you need to migrate them, re-using is no option.
    For data download you can use reports and OWLs. In addition SAP offers services to extract data with tools.
    Before the upload
    • Please check especially with respect to Fixed Assets, that the right values are used. Also the Fixed Asset IDs cannot be re-used.
    • Ensure that the old bank accounts data are not valid any longer (otherwise bank statement processing will determine the “old” bank accounts and clear old items)
  6. Add the new company specific data to the master data for the new company.
  7. All employees have to be transfered to the new company
    unfortunately “fire and re-hire” is the only option.
    Recommendation: define a new determination reason, e.g. “Reorg” to see the transfers for the re-org.
  8. Update User Access Rights:
    You have to ensure, that the employees can only create and edit data for the new company. So check the access rights of all your employees.
    For self services the new cost centers will be defaulted.
  9. Last but not least: Delimit the old company by maintaining the end date
    The validity of an organizational unit is considered when creating new data. So you will get an error when creating e.g. POs for the old company.

Feedback is welcome.

    Update October 2017:

    SAP Cloud Service Center offers a service, which under certain conditions allows the change from one fiscal year variant to another fiscal year variant. If you are interested in such change, please raise an incident or drop an email providing the following information:

    1. Which productive tenant?
    2. Old Fiscal Year Variant, new fiscal year variant
    3. Change per
    4. effected companies and set of books.


    1. Changes use shortened fiscal years. Fiscal years are numbers in a row. The shortened year will always get the next number in the row. 2017, 2018, 2019 …
      e.g.If you change from “Jan – Dec” to “July – June” on Juli 1st 2017, then Jan – June will be Fiscal Year 2017, July – June 2018 will be 2018.
    2. If there are postings postings for certain periods, then the change might be impossible.
      e.g. If you have posted a document for the example above with posting date 13.7. the period old was 7/2017. The new will be 1/2018. Such change is not possible.

    Marlene Katzschner – We were recently acquired and will need to switch from a fiscal year to a calendar year. We have just under 550 employees in byD and a large amount of engineering and manufacturing data. Before I submitting an incident I need to learn more about this process. Would you be the correct person to get in touch with directly? I need to plan this internal project out and in order to do so I need more information about the process.
