insert into table navision

urgent :
how can I create a new custumer (code name) in the table navision custumer when I click on
button, I want to know the C / AL as trigger on-push???

There is already a button on the toolbar “Insert (F3)”

then click the customer number field.

If you have the number series set for Default Nos. it will give you the next number in line.

what are you trying to do?
