Example: Inserting and replacing offers with a single currency

The data load utility provides two modes for loading single-currency offers. Use the insert mode when adding a new offer that previously did not exist in the database. Or use the replace mode when replacing an existing offer with a different offer. The behavior of each mode depends on whether the identifier is specified.

Insert mode

Identifier specified: The insert fails if an offer with the same combination exists in the database.

Identifier not specified: Offer is inserted successfully.

Replace mode

Identifier specified: Updates the specified offer according to the Identifier. If offer with the Identifier does not exist in database, the offer is inserted.

Identifier not specified:

If the number of records with same pair in database is one, updates the existing offer directly

If the number of records with same pair in database is greater than one, deletes all existing offers; then inserts the new offers from the CSV file.

CSV file with sample offer data for a single currency

The first row in the CSV file can also be column names, which depends on the firstLineIsHeader attribute in the price list data load configuration file. The firstLineIsHeader is an attribute of <_config:DataReader> element.

firstLineIsHeader

true

Indicates that the first line in the CSV file is treated as column name data, and it is not inserted into the database.

false

Indicates that the first line in the CSV file is data to be read and inserted into the database.

In this example the data source is a CSV file named SingleCurrencyOfferGroup.csv. The file contains sample offer data. Each column is delimited by a comma.

CSV file column definitions

The column order is defined in the offer data load configuration file. See the number attribute in the <_config:Data> element.

PriceListUniqueID

(Optional, String) The identifier of the price list. When there is a data mapping for price list UniqueID in the price list data load configuration file, then the uniqueID is mandatory in the CSV file.

PriceListName

(Optional, String) The name of the price list that contains this offer. When loading an offer, the price list name or price list UniqueID is optional. When both of them are not provided in the CSV file, the store's default price list name is used to load. If one of them is provided, the provided price list is used to load. If both of them are provided in CSV file, the price list uniqueID is used to load.

CatentryUniqueID

(Optional, String) The unique identifier for the related catentry. When there is a data mapping in the offer data load configuration file; then the CatentryUniqueID is mandatory. If both of them are provided in CSV file, the CatentryUniqueID is used to load.

CatentryPartNumber

(Mandatory, String) The part number of the catalog entry that this offer is defined for. When loading an offer, the CatentryPartNumber name or CatentryUniqueID is mandatory. When both of them are not provided in CSV file, the offer fails to load. If any of them is provided, the provided catentry is used to load. If both of them are provided in CSV file, the CatentryUniqueID is used to load.

Identifier

(Optional, String) The identifier of the offer. If not specified in the input file, it generates a random identifier for the offer.

Precedence

(Optional, Double) When more than one offer is effective at a particular time, the one with the highest precedence is used. If not specified in the input file, it sets a default value of "0.0".

StartDate

(Optional, Timestamp) The start of the time range during which this offer is effective. Use the format yyyy-mm-dd hh:mm:ss.millis.

EndDate

(Optional, Timestamp) The end of the time range during which this offer is effective. Use the format yyyy-mm-dd hh:mm:ss.millis.

QuantityUnitIdentifier

(Optional, String) The unit of measure for Minimum Quantity and Maximum Quantity.

MaximumQuantity

(Optional, Double) The maximum quantity that can be purchased in a single order under this offer.

MinimumQuantity

(Optional, Double) The minimum quantity that can be purchased in a single order under this offer.

LastUpdate

(Optional, Timestamp) The last time that the offer is updated. Use the format yyyy-mm-dd hh:mm:ss.millis.

Description

(Optional, String) The description for this offer.

Price

(Optional, Decimal) The price of the offer in the desired currency.

Currency

(Optional, String) The currency specified for the offer price.

Map data

The following snippet from the sample configuration file demonstrates how to map each column of data in the source CSV file to a value.
<_config:DataSource>     <_config:Data>         <_config:column number="1" name="PriceListUniqueId" />         <_config:column number="2" name="PriceListName" />          <_config:column number="3" name="CatentryUniqueId" />         <_config:column number="4" name="CatentryPartNumber" />         <_config:column number="5" name="Identifier" />         <_config:column number="6" name="Precedence" />         <_config:column number="7" name="StartDate" />         <_config:column number="8" name="EndDate" />         <_config:column number="9" name="QuantityUnitIdentifier"/>         <_config:column number="10" name="MinimumQuantity" />         <_config:column number="11" name="MaximumQuantity" />         <_config:column number="12" name="LastUpdate" />         <_config:column number="13" name="Description" />         <_config:column number="14" name="Price" />         <_config:column number="15" name="Currency" />     </_config:Data>
</_config:DataSource>
The number attribute in the <_config:column> element, defines the column order in the CSV record file. The name attribute defines the column name used in the <_config:DataMapping> element.
The following snippet from the sample configuration file demonstrates how to map each value to a business object logical schema path.
<_config:DataMapping>     <_config:mapping xpath="PriceListIdentifier/UniqueID" value="PriceListUniqueId" valueFrom="InputData" />     <_config:mapping xpath="PriceListIdentifier/ExternalIdentifier/Name" value="PriceListName" valueFrom="InputData" />  
<_config:mapping xpath="PriceEntry[0]/CatalogEntryIdentifier/UniqueID" value="CatentryUniqueId" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/CatalogEntryIdentifier/ExternalIdentifier/PartNumber" value="CatentryPartNumber" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/Qualifier" value="Identifier" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/Precedence" value="Precedence" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/StartDate" value="Start Date" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/EndDate" value="End Date" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/QuantityUnit" value="QuantityUnitIdentifier" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/MaximumQuantity" value="MaximumQuantity" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/MinimumQuantity" value="MinimumQuantity" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/LastUpdate" value="LASTUPDATE" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/Description/Value" value="Description" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/Price/Value" value="Price" valueFrom="InputData" />     <_config:mapping xpath="PriceEntry[0]/Price/Currency" value="Currency" valueFrom="InputData" />
</_config:DataMapping>
The value attribute in the <_config:DataMapping> element must be consistent with the name attribute of the corresponding item in the <_config:column> element. Both attributes are case sensitive.
