Just consider a case where in we wish to update Employee Details.
We will take input as EmpID from user, display record for the entered EmpID . On hitting say enter key, we need this Emp Id, Emp Name (textbox/control) to be disabled as for a given employee in a given organization, these would always remain the same. But rest fields such as phone, designation should be unprotected/Modifiable at run time.
Also when user just enters EmpId all the other fields should be disabled(protected).
PS: We believe AD, DY may be of some use to us but not sure how to implement the same at run time on a Natural MAP.
Also, we would like to know how to enable/disable PF keys at run time using a Natural Map.
For example, say user hits Enter key and wishes to update a record, hence Enter key should now be disabled, until update key is not hit. Once update is done, Enter should be enabled and Update can be disabled.
