Effect of change setting in OBA5

Hi Friends,

Do we have any side effects if we set BK 134 in OBA5 to a warning? Because I set this to a warning this is valid for the whole system.

I change setting for BK to warning because when i running FAGL_FC_VAL there are gl that valuation value cannot be posted because document transaction have co account and different profit centers. Your help is greatly appreciated.

Thank You
