Changes in Access 2010 (linked tables with multiple value fields)

I have upgraded to MO 2010 from MO 2007. In Access 2007 I have created a database which i split between a back-end and a front end. After migrating to 2010 I get an error message when updating links to tables which contain fields with multiple values:

"[table] is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long"

When I remove the fields which allow multiple values from the backend it is possible to update the links (but I don't want to remove these fields).

Is there anyway I can keep the multiple value fields and still refresh links?

I don't know of any developers here who use these new fields.

See here:

Under:
"What's mixed (good and bad)"
and:
"What's broken (new bugs)"

Also, these fields do not translate directly into any SQL Fields, so you will not be able to easily upgrade to SQL server when the time comes.

If you go back to the basics and create your Many-to-many tables manually, then what you are trying to do should work fine.

Let's see what some other Experts have to say...

Thanks Jeff,

I have now rebuilt my old BE (I had to do this on a computer running Access 2007 in order for it to work). The disadvantage is that I now need to add two additional tables to my query - which is a problem as I seem to recall there is a limitation in Access that limits a query to three steps/tables in order for it to remain updateable. Anyway, I will try to work around this as well.

Best regards

<The disadvantage is that I now need to add two additional tables to my query>
Yes, but the advantagea are that it will:
Work flawlessly.
Be exportable
Not have any issue
Be easier to understand
Be Standardized
...ect


<I seem to recall there is a limitation in Access that limits a query to three steps/tables in order for it to remain updateable.>
Not exactly, the types of Joins, for the most part, determine if the query is updateable or not.
The attached database query has 4 tables, and it is quite updateable (can create an order)
(the Cust Name and Product Names even fill in automatically)
