Just to be sure I understand:
You have a table "AUDIT NOTES" that you exported to Excel and made changes. You imported the changed Excel data to a table "Test Update". Now you want to update the records in "AUDIT NOTES" with the changed records in "Test Update".
Change your update query to a select query and execute it. I would bet 0 records would be returned.
Be aware that "Note" is a reserved word in Access and shouldn't be used for object names. Since you have a field named "Note", it must be delimited with brackets.
In the update query you have linked each field in "AUDIT NOTES" with the matching field in "Test Update". Since the data in "Test Update" is different than "AUDIT NOTES", no records should be returned.
When you exported the fields from "AUDIT NOTES" to Excel, did you include the PK field?
When you imported the changed data, did you include the PK field in the import and NOT let Access create a PK field?
If you did, I would try something like
Code:
UPDATE [Test Update] INNER JOIN [AUDIT NOTES] ON
([Test Update].ID = [AUDIT NOTES].ID)
SET
[AUDIT NOTES].RESOLUTION = [Test Update].[RESOLUTION],
[AUDIT NOTES].[LOGGED BY] = [Test Update].[LOGGED BY],
[AUDIT NOTES].[NOTE] = [Test Update].[NOTE],
[AUDIT NOTES].DeptResponsible = [Test Update].[DeptResponsible],
[AUDIT NOTES].[Source code Desc] = [Test Update].[Source code Desc],
[AUDIT NOTES].Res_Type = [Test Update].[Res_Type],
[AUDIT NOTES].[ERROR CATEGORY] = [Test Update].[ERROR CATEGORY];
Linking the two tables on the PK field will ensure the correct record gets updated with the correct changed record.
