Creation Of Maintannace View

Question

Hi All,
My requirement is i need to create table maintanace view using one ztable. in this table i have one key field. Name of the key field is 'GUID' remaining fields are APPLN, APPLN TYPE,PARTNER NUMBER. These 3 fiedls non key fields. My requirement is while creating the view and i need to follow following instructions
Do not define the GUID as the key. Place the GUID at the end.
The key could be APPLN, APPLN PARTNER, TYPE, START DT, END DT the same as key for which we validate the duplicate entries.
anybody can tell me how to define key for fields APPLN, APPLN PARTNER, TYPE, START DT, END DT . These fields are non key fiedls in ztable while creating the view we need to display as key fiedls and i have remove key for GUID field.
anybody can suggest me what shall i do in this case.
thanks,

You should go back to whoever has asked you to do this and tell them it is a stupid requirement!  If they have a Z table with a certain structure and key fields why do they want to maintain that table with different key values?!  It won't work!
If they want the key values to be APPLN, APPLN PARTNER, TYPE, START DT, END DT as you suggest then the underlying Z table will have to have those set as the key fields.  If GUID is the key on the Z table but not in the maintenance screen, what will you do if a user enters a duplicate GUID?  You would have to write a lot of validation logic and probably a custom transaction to achieve this which is simply pointless!
