Access the material master record in Create or Change mode, and select the user department Basic Data .

The Basic Data screen appears.

You now have the following options:

- If EANs (International Article Numbers) are assigned internally, specify an EAN category, but not an EAN. The system determines the EAN automatically when you choose Enter .

- If EANs are assigned externally, specify an EAN. If you do not specify an EAN category, it will be determined automatically when you choose Enter .

If the EAN has the EAN category for UPC-E (Universal Product Codes displayed in a contracted form), you must also specify the EAN category, but only if the EAN category for normal UPCs is also used in your system. For more information, see the documentation for the activity Define Attributes of EANs/UPCs in Customizing for the Material Master .

The EAN here always refers to the base unit of measure, as does any gross weight or volume that you enter.

To enter packaging data (such as dimensions, volume, and gross weight) for the EAN for the base unit of measure, choose  Additional data Units of measure . You can access this function from all user department screens. Any values for gross weight and volume that you have already entered on the Basic Data screen for the base unit of measure are displayed on the screen that appears. You can now enter all valid units of measure for the material. For each unit of measure, you can specify an EAN or EAN category, and also packaging data. The EAN for each unit of measure on this screen is the main EAN.

To return to the Basic Data screen, choose Back .
