When you create a catalog folder, catalog, category, product, or SKU, you can specify values for its attributes in the New Item dialog box. After you create the item, you can modify these values.
Note: For some properties, you cannot enter the value directly. For example, some properties are Boolean values, in which Core Commerce provides a drop-down menu where you select either True or False. If the property represents another repository item or is a collection of repository items, you cannot enter a value in the field directly. Instead, click in the field, and then click the ... button to open a dialog box where you can specify the item or items.
From the ATG Control Center main navigation menu, select Catalog Management > Catalogs.
Select the item you want to edit in the catalog tree. If editing a SKU, select the product, then select Skus from the menu at the top of the window.
Select Properties from the menu.
The ATG Control Center displays a table where you can edit the attribute values directly.
Enter a value next to the property you want to edit.
After editing the catalog item, select File > Save.
