SYMPTOMS
You export a table from Microsoft Office Access 2007 to a list in Microsoft Windows SharePoint Services 3.0. When you do this, the original data of the primary key column is not in the Data View of the list.

This issue occurs when the data type of the primary key column of the Access 2007 table is one of the following data types:
 * Number
 * AutoNumber



CAUSE
This issue occurs because Access 2007 exports the data of the primary key column to a new hidden _ID column. By default, the _ID column is not added to the Data View of the SharePoint list.



RESOLUTION
To resolve this issue, add the hidden _ID column to the Data View of the SharePoint list. To do this, follow these steps:
 * 1) Connect to the Windows SharePoint Services 3.0 Web site that contains the exported table.
 * 2) In the View All Site Content pane, click Lists.
 * 3) Click the SharePoint list that contains the hidden _ID column.
 * 4) Click Settings, and then click List Settings.
 * 5) In the Views section, click All Items.
 * 6) In the Columns section, click to select the Display check box of the _ID column, and then click OK.



MORE INFORMATION
When Access 2007 exports the primary key column data of a table to a SharePoint list, a new primary key column is created. The new column is assigned the name &quot;ID&quot; and the AutoNumber data type. The original primary key column is assigned the name &quot;_ID,&quot; and is not assigned the AutoNumber data type.

When the table is exported, each record is assigned a new unique key value in the ID column of the new SharePoint list. The original data of the primary key column is moved to the hidden _ID column. Therefore, the export process can be confusing, because the primary key column names are switched and because the original primary key column data is hidden.
