You have the following options for preparing master data:
Manual selection
To prepare master data manually, proceed as follows:
By defining selection criteria (for example, articles, EAN/UPC or merchandise categories), you can specify that the system should only prepare data for certain articles. If you do not restrict the preparation, the system prepares the data for all articles in the selected stores.
A list of the IDocs created is displayed.
Change messages and full versions
If you want to prepare master data or create a full version via change messages, proceed as follows:
In the Control check box, you can select parallel processing. This is recommended if a large number of recipients (for example, hundreds of stores) receive assortment lists. You can enter the server group to be used.
The initial screen is displayed.
The system lists the IDocs that you have created.

Before you can prepare change messages, you must have successfully initialized a full version for the store concerned.
