Hi James,
I'm not sure if I understand you problem correctly. My problem with the data extraction for france was that I missed the content of 2 columns of TXW_FI_POS in the extraction file. This was caused by a coding error in the coding that came along with the SAP note 1906078. The note 1990639 fixes this coding error so that the 2 columns are now filled correctly.
Maybe you can add some screenshots to describe you problem in detail?
Be aware that you have to set the language key to "FR" when you are going to extract the data via transaction FTW1A.
Regards,
Stefan
