G/L date change after reversing receipt

Hi All,

We want to reverse receipt at 30/12/14.

User already input 30/12/14 for G/L date, and doing reversal without any error.

Then we check its batch in P0911 and we found that G/L date change into 11/02/15 (today date).

How can it happen?

User tries to receipt and reverse again, but the result is still the same.

We have to reverse it at 30/12/14. What should we do?

I'm appreciate your help.

Thanks,

Kinan
