COPA - operating concert

Hi gurus,

I'm not sure if the process of the operation concern is as follow:

When you create a operation concern (in my case RU00) some new table are created by the system CE1RU00, CE2RU00,... to hold the data

When you run the transaction KE24 it shows an ALV. To create the ALV use a standard program but this program has been created when you created the operation concern using the program RKEVRK2C as template. The program name is in my case RK2CRU00.

What I need is modify the ALV, (the format of a field) and I didn't find any badi or user exit to do it.

Do you know how/when to create the program RK2CRU00? Maybe in the creation point I can modify the format .

Can somebody help me?

Thank you in advance,

Manuel
