I have created ztable with 5 fields which are
plant, material type, material group, created by user and changed by user.
out of which I created plant, material type, material group as primary keys
So I went to sm30, and created a record.
Again when I try to edit that record like plant, material type, material group are in disable mode.
Is that because of I have maked as primary key fields ?
If so, what to do to make these fields editable ( also on more thing is how many primary key fields mimimum I can keep in this case) ?
Thanks in advance...
