Once you have implemented an enhancement point or you have just been given
the enhancement implementation name and do not know which program it is contained in you need to use one
of the following transactions to access the details.
SE20
The first is t-code SE20 which is the dedicated stanalone transaction for managing enhancments of this type
including enhancement spots, enhancement implementations and BADI's.
SE80
The second is t-code SE80 which is the transaction im sure everyone uses now to access any development
object type including enhancments.
Alternatively if you have the latest version of SAP you can just put your object in the
top level development object field and it will work out what it is and open the correct screen
