Once products have been added to a channel and you are familiar with the different views and how to filter. The next step in the process for syndication is to map your master data ( the data that has been imported into PDX) to the attributes in the channel. As you are mapping, you will need to work through the following tasks:
-
Ensure there are values in all required fields.
-
Ensure all formats match, with no errors on the attributes.
-
Prepare, if applicable, to add additional attributes that may not be required but are normally sent to the retailer site.
Mapping can be performed from the grid view in a channel category to map one attribute at a time or from a mapping screen for a quick way of mapping all attributes within a category.
Note: Attribute mapping does not apply to all language layers when first set, only the master language. Mapping for language attributes must be completed in a separate process for each applicable language.
Mapping through product view
To map an attribute from the grid view of a channel category, click the down arrow by the selected attribute to open the dropdown menu and select Map attribute.
When 'Map attribute is selected,' the option to map data to that attribute will appear. The left-hand side of the screen will show a list of attributes that were imported into master data. The right-hand side of the screen will show help text regarding the channel attribute. The user can use the search option 
if all or part of the attribute name is known or scroll through the left-hand side list to find the desired attribute.
Once an attribute has been mapped, it will now show in the dropdown for that attribute and the master data values will be populated into the cells of the channel attribute.
Mapping through mapping screen
To open the mapping screen for a channel category, click on the 'Mappings' icon as shown below. This icon will appear in both the list view and the grid view.
This will open the main mapping screen, which shows the following: a column of channel attributes that have not yet been mapped, a column of all master data attributes that have been imported, and any existing mappings of channel attributes to master data attributes. Additionally, the gray columns on the right-hand side of the mapping screen provide descriptions of the channel attribute selected and the master data attribute selected.
Both the channel and the master data columns have a search option, which can be opened by clicking 
. The data view can be modified in the channel column to help specify which attributes to locate.
To map channel and master data attributes, select the pair to link. Then click the mapping link to the right of the value in the master data column.
Once the mapping has been created, it will appear in the 'Your mappings' section on the mapping screen. To complete the process, click the 'Done' button. To remove any mappings that appear in the 'Your mappings' section, simply click the 
to the right of the master data value.
