add new value - not modify existing values

Karen

I want to give the user the opportunity to add a new value when looking up the form but they may not have the opportunity to modify the existing values

if I set the following props:
Editable: True
InsertAllowed: True
ModifiedAllowed: FALSE
People still can change the existing values

if I set the following props:
Editable: FALSE
InsertAllowed: True
ModifiedAllowed: FALSE
People can't add a new values

In the "OnModifyRecord" of the form, put

EXIT(FALSE);
or
ERROR('You cannot modify the record');

the ERROR may be better because with that the user knows his action was refused.
PS : the error should have a global constant, not the string like in my example.

But I don't get the error when I put it in the onModifyRecord()

If you want an error, you must just put the ERROR-statement, not the EXIT(FALSE) statement. If you put the EXIT-statement, Navision will not process anything beyond the EXIT-statement.

It only gives an error when I put it in the onRename() of my table

But how can I replace the changed value back into the old (previous)
value

I tried to use:

OnRename()
VeldA := xRec.VeldA;
Error('...');

But in my table I can't do an update. Is that the reason why the value won't be replaced?

The only thing you have to do is to put some code in the form.

Form - OnModifyRecord() : Boolean
ERROR('You cannot modify the record');


With this, you can insert, but not modify

But you also need to put the property "DelayedInsert" to Yes. Otherwise when filled in the key-value, Navision Saves the record (=insert) and it is not possibile anymore to add a description.
