Error of validation rule in a project.

Hi All,

I am getting an error while creating a wbse in a project and saving it. I found that validation rule is created for wbse:

PROJ-PROFL = 'ZME0001' (Prerequisite)

PRPS-POSKI = PROJ-PSPID :1-9: (Check)

Check the project coding mask consistency. (message if check fails).

Now, i am creating a project definition for profile ZME0001 and saving it . Then , i open the project and add wbse on level 1 with same id as project definition i.e AA-UP/11/001 and when i am saving it system gives me an error message defined in validation rule, i tried by restricting the lenght of wbse short id to 9 but it doesnt work.

please let me know where i am doing wrong.

Thanks
