If the PK is an Access AutoNumber (?), then it cannot be changed.

Thanks, DatabaseMX.  

I really don't want to change the key.  I want to replace the key with another, valid PK.  For example, I want to modify a transaction record so it points to The Home Depot, instead of  Lowes.

Then something seems awry in your design...

For example: If you are a shipper and you want to change the ship destination from Home Depot, to Lowes.

The you have a "Stores" table:

tblStores
StoreID (Primary Key)
StoreName
...ect

..Then you have a shipments table

tblShipments
ShipmentID (Primary Key)
StoreID (Foreign Key)
ShipmentDate
...etc

These two tables are linked in the relationships window on "StoreID", and Referential Integrity is enforced.

In this case, it is quite easy to change the StoreID in the shipments table to another StoreID, without issue.

So you will have to explain to us the design and relationships between your tables.
Also provide us with the details of how and where, exactly, you are trying to change the ID.

Guess I'm not quite following.  Maybe Jeff has explained what you are after?

Changing a value in a key field might result in a violation of normalization.  We need more information on what you are trying to do, in terms of tables, fields and relationships.

Thanks - I really appreciate your interest in my problem.
Jeff described my situation well.  I have a tblStores with fields StoreID (primaryKey, auto-number) and StoreName.  tblShipments contains a foreign key (also called StoreID) in order to retrieve StoreName via an ACCESS relationship.  I expect the relationship to maintain referential integrity.

In my system, I use a query to retrieve fields  from tblStores and tblShipments, and that query is the recordsource for my form. I sometimes detect an improper StoreName. Example: a tblShipments record shows Home Depot and I want to change it to Lowes.  Using VBA, I retrieve from tblStores the Lowes StoreID and I want to assign the Lowes StoreID to tblShipments.StoreID.  ACCESS replies with runtime error  '-2147352567(80020009)', "To make changes to this field, you must first save the record".

The actual VBA that causes the error: me.StoreID = longStoreID.  I am trying to make this change by assigning the correct StoreID to the foreign key (displayed but not enabled) in the form.

I am learning this stuff as a retirement hobby, so my education is weak in many areas.  30 years ago I programmed in COBOL.

Helen/ MX/ Jeff -  Could it be that I have to delete the inaccurate record and then add a new, correct record?  If am comfortable with DAO, but is there a way to manipulate the data in the underlying query without messing up the flow of the form?

Unless you also assigned StoreID in the shipments table as Primary key, I can't see what the problem might be...

You did not say by what method you are assigning longStoreID, but in a global sense you may want to use a combobox.

Here is a very simple sample, there are no problems with changing the store.

DatabaseMX -

If I cannot change a field that is a Primary Key, then the solution is to delete the child row and then re-add a replacement child row with new info (allowing ACCES to provide a new PK) ?

Thanks.
