Greetings everyone,

I'm trying to read from a page web service published in NAV but it is giving me a "Callback functions are not allowed" exception. The published page is Item Card with its default operations. How can I handle this exception?

Thanks in advance.

I believe the item availability action is causing you that issue because it uses Page/Form to perform the action, try with Item List page and see if you can duplicate the issue.

I controlled C/AL code of the item card page but i can't find any function(like create, update etc.) causing those dialogues. So I don't know where to put the "if guiallowed then". Is there any way to find where to put this statement ?

open the item card and try to populate the fields manually. you'll see that form will open up in one of the fields. change the code to if guiallowed then,
