Hi Experts.
I'm in trouble.
I have to set EXIT that can control "CostCenter" or "CostCenter Group" in KP06, KP26, KP46.
For Example in KP06,
if a user inputs cost-center value "100000" in cost center field,
then error message(error) display below screen (Ex> "It's not correct !!).
I tried again with Enhancement "COOMKPT4", "COOMKPLV".
But It's not working.
(I think it's not suitable for KP06, KP26, KP46. Is it right?)
And I tried with FIELD-EXIT, but the result is same.
(and I tried with GGB0, and the devil knows what, the result is same..)
I'm in trouble.
Please help me.
I must set EXIT (or any ways) for KP06, KP26, KP46.
(Properly speaking, for costcenter for above T-codes)
I want your detailed explanations to solve this trouble
Thank you and best regards.
Mr.Kim.
