BADI Convertion

Hello!

Experts, testing in the new version ECC 6.0 one BADI implemented in 4.6C we discovered that it wasn't working at all. In transaction SE19 I tried to active it again and a screen appeared asking for a convertion, wich I did (I had to create a new implementation). After that the BADI started to work again.

Does anyone know why it happened? I'm concerned that it could happen again...

Thanks!
