Question: Is there a similar way to get the next ID for a table in SalesLogix Web as the getIdFor function in the SalesLogix Windows client?
Answer: Take a look at this article –

Use the C# example.
Use the entityfactory…
..SO for a new contact when working with an entity,
<Sage.Entity.Interfaces>.
con.Porperties…..etc.
con.Save();
This will give you a new Contact with a new SalesLogix ID.
Also, see this post if you do need to generate a new table ID apart from the automatic creation that occurs when adding a new entity record.
