thanks for the answer
I couldn´t find the way of disable LIFRE field, which is in the details tab of the MIRO transaction.
I also used the transaction OLMRLIST to creat a variant but I couldn´t find the field LIFRE.
There are any other options?
Thanks in advance for the help
You can use SHD0 or OLMRLIST, it both serves the same purpose.
I think you are unable to find the fields you require because you need to select the correct program and screen.
Go to System --> Status
Then, take the Program (subscreen)
and screen number.
If you use the main program and screen, you would never find fields like Inv. Party
This should solve your problem.
