Automatic inversion not working in period 1 of new fiscal year

Hello all,

We have a reclassification task with document type 1C. For this task, we want the documents to be automatically inverted in the following period, before the task is run again.

I have set up document type 1C as "automatic inversion also in new fiscal year".

While we are in a given fiscal year, the reclassification is working as expected, i.e.:

• Period initialization task reverses prior period documents 1C
• Reclassification task posts new documents 1C

When we get to January, however, it does not work. Period initialization does not reverses the 1C documents from period 12, and we get the message "processing not necessary".

I checked the SAP documentation and it looks like the only configuration needed is the "inversion" setting on the document type, which I have made.

Does any of you have an idea of how to make this work?

Thank you in advance.
