Sorry, I guess I may have omitted some information by assuming that you would have already done it.
When you create a new table you would need to, in the frontend, use the ImportLink of the table just like linking any table that you would if want to link to it. You would of course have already done this in the frontend because you had it ready to move to production. At least that is what I assumed. So I'm a bit confused as to what you have and what you have not done. So, from the beginning:
1. I find that I need to create some new tables in the backend and add some fields to others.
2. I create my tables and add fields to my tables in the development backend.
3. I import my new tables (by linking) into the development frontend and the new fields in the other tables should automatically be there in the linked tables which had existed previously. But if you are using any SQL Statements in queries or forms or reports which do not use the Select * FROM Table Name, then you would need to go modify those in the frontend for the new stuff to show up.
4. So once all of the development stuff is complete, I need to move my changes to production. I will use the method we talked about in the further steps.
5. I go to my production backend and then I add the fields manually to the tables which needed the new fields.
6. I then, while I am in my production database, import the new tables that didn't exist before (not link) from the development backend.
7. Next, I need to add the data to the new fields that were added to the existing tables, so I am going to need to use an UPDATE query instead of an Append query. Because the New tables didn't exist before they can just be imported to the backend from the development backend.
8. I will link the tables that have new fields but existing data in other fields by being in the production backend and then doing the link to those tables in the production database.
9. I then create the update by going to the Query QBE grid. You get there by clicking CREATE > QUERY DESIGN. I Add the tables - the one which is from the production db and the one from the development db.
10. Join the two tables using the PK field.
11. I select the fields from the production version table, which need to be updated, into the grid.
12. Then I change the query type to UPDATE (from going to the View menu or tab).
13. Next I will put the table name and field name from the linked development backend in the UPDATE spot in the grid like this: [TableName].[FieldName]
(changing to the actual table name and field. For example if I had linked my table named tblLookups from the dev backend it would be likely named tblLookups1 and let's say my field name is Preference, which I need to update. So I would put in the UPDATE spot in the QBE grid, it would look like:
Once I have done that for all of the fields I need to update, I will then unlink my dev backend from prod backend and then take my frontend and relink to the prod backend and THEN the linked table manager should work when you link to it from the frontend.
Just a reminder - the Linked Table Manager is ONLY for RELINKING tables that have ALREADY been linked.
