we have a requirement where we are unable to create a Z for transaction SE16.
I went to se93 and checked it was a function pool so i went to SE80 to make a copy of standard function group SETB to ZSETB.
it made a copy of it anf I copied all the FM's and made a Z of those.
Once it is done. When I activate it it give a lot of errors , I have checked it and made sure that it is copying entire Function Group but all are fine.
My system is ECC6.0, earlier we had ZE16 which is a replica of SE16 and this had a lot of problem like ending in dumps , so we thought we would make a new Z transaction for SE16, but we get many error.
Please try it out once in ur system before U suggest me a change to be made.
