It appears that if you attempt to carry forward a T2 of a related group and one of the related groups T2 is open in Taxcycle, the program wants to refresh the carry forward resulting in the related T2 that was open being over written by the carry forward of the first T2.
Basically, if you are Carrying forward a T2 in a corporate group and get the following message
Click “No” and close the other T2 and try again and every thing works fine.
This error does not appear to happen if you have an unrelated T2 open.
An aside.
Is the proper terminology “Carry forward”, “Carry-forward” or “Carryforward”
The message has both “Carry-forward” or “Carryforward” in it.
