Date conversion problem !

Hello,

I used tc FB01 to input document via BDC , in the past the document date format that I input is : YYYMMDD and then it is converted into DD.MM.YYYY in the input screen , but now when I input YYYYMMDD in will be converted to YY.YY.MMDD So the transaction will be always in error . So here how I can adjust this problem ( Input YYYYMMDD ==> DD.MM.YYYY) ....

Thanks,
