Error while using Tcode MB1C

Hi

I want to add initial stocks to plant zs10 using movement type 561. But I am getting an error stating "Account determination for entry 0009 GBB ____ BSA 3000 not possible". I went into Tcode obyc for chat of account 0009 but I don't know how to proceed with this. Can anyone tell me how to rectify this error.

points will be awarded

thanks in advance
