Example: Relationship data for SKUs and products

Use the Data Load utility to efficiently replace, or delete existing relationship data between multiple products and SKUs.

This example uses a CSV file to demonstrate how to insert, replace, or delete your data. You can also create and use an XML formatted file to insert, replace, or delete your data. If you choose to create and use an XML formatted file, ensure that your XML elements use the same names as are used for CSV column names.

CSV column and XML element definitions

PartNumber: Required: (String) The unique part number of this catalog entry. This field is cannot be NULL and it must be unique. The part number for a catalog entry displays in Management Center as the value for the catalog entry Code property.
Sequence: (Double) An optional number used to control the order in which the items appear under the parent product.
ParentPartNumber: Required: (String) The catalog entry identifier of the parent product of the SKU.
Delete: (String) A flag indicating whether to delete. Specify 1 to delete the row.

Other optional fields not included in the example are:

ParentToChildCatEntryRelField1: (String) A user-defined field available for customization of the parent product to child SKU relationship.
ParentToChildCatEntryRelField2: (Integer) A user-defined field available for customization of the parent product to child SKU relationship.
ParentToChildCatEntryRelField3: (Double) A user-defined field available for customization of the parent product to child SKU relationship.

230093	2	3004	1

Mapping data

The following code snippet from the catalog entry products SKUs relationship loader configuration file demonstrates how to map each value to a business object logical schema path.

<_config:DataMapping>
	<_config:mapping xpath="CatalogEntryIdentifier/ExternalIdentifier/PartNumber" value="PartNumber" />
	<_config:mapping xpath="ParentCatalogEntryIdentifier/ExternalIdentifier/PartNumber" value="ParentPartNumber" />
	<_config:mapping xpath="displaySequence" value="Sequence" />
	<_config:mapping xpath="" value="Delete" deleteValue="1"/>
</_config:DataMapping>

If you perform an insert or replace operation, do not specify the "Delete" column in the CSV file or you can leave the "Delete" column empty.

Business object mediator

The mediator class name is com.ibm.commerce.catalog.dataload.mediator.CatalogEntryParentProductMediator.

Note: When you use a mediator that is provided with HCL Commerce with the Data Load utility, the utility assumes that you are loading data for all columns for a business object. If you want to update the data in only specific columns, configure a column exclusion list for the load process. A column exclusion list causes the Data Load utility to ignore specific columns during the load operation. If you do not use a column exclusion list, the utility updates all columns in the row of a database table row when the utility updates the row. If no value is set in the input file, the utility can replace the existing column value with a default value or set the value to be null. For more information, see Configuring a column exclusion list.
