For catalog imports, it also logs a `Phase 1 - Items` and `Phase 2 - Relations` message. For each type of item, it prints this message: ``` Processed N elements successfully ``` where: `N` number of elements processed name of the data type, like product, catalog It also prints the total number of elements: ``` Processed N total elements ``` ## Process Errors Process errors can occur during import and export processes. They include missing or incorrect process parameters, problems while acquiring locks, malformed XML feeds, and general system errors. Process errors sometimes cause an import or export process not to start or to abort immediately during execution. ## Data Errors Feeds cause data errors and data warnings, which occur only during an import process. They are always local to an element in the feed. The import process isn't aborted when a data error or warning occurs; instead the import process skips the invalid element. Thus an import process can end with no process error but with a data error. Problems with data are classified as DATAERROR or DATAWARNING. More details about the location and cause of the error or warning are provided in the log file.

Error Type	Description
DATAERROR	Logged when an element in the feed (for example, category or product) can't be processed at all. For example, the element lacked a mandatory ID attribute. There is at most one DATAERROR logged per element in an import feed.
DATAWARNING	Indicates that an element was processed, but only partially. For example, a feed element comes with a custom attribute, but the attribute isn't defined in the system. In this case, the custom attribute is ignored. Another example is that a product references a classification category that doesn't exist. In this case, no classification category is defined for the product. There can be multiple DATAWARNINGs per import element in the feed. The use of obsolete elements or subelements is logged as DATAWARNING

Error Type

Description

DATAERROR

Logged when an element in the feed (for example, category or product) can't be processed at all. For example, the element lacked a mandatory ID attribute.

There is at most one DATAERROR logged per element in an import feed.

DATAWARNING

Indicates that an element was processed, but only partially. For example, a feed element comes with a custom attribute, but the attribute isn't defined in the system. In this case, the custom attribute is ignored.

Another example is that a product references a classification category that doesn't exist. In this case, no classification category is defined for the product.

There can be multiple DATAWARNINGs per import element in the feed.

The use of obsolete elements or subelements is logged as DATAWARNING

Import pipelets provide easy access to the number of DATAERRORs and DATAWARNINGs using the _Status_ object. In the following example, a script uses the status object to count errors. `var dataErrors : Number = status.details.DataErrorCount;` `var dataWarnings : Number = status.details.DataWarningCount;` It's a good practice to determine the success of an automated import process by first checking for process errors, then for DATAERRORs, as shown in the following script code. `var success : boolean = (status.code == 'IMPEX-0') && (status.details.DataErrorCount == 0);` Code shouldn't treat the occurrence of DATAWARNINGs as an unexpected error, because a feed that doesn't cause DATAWARNINGs today can cause DATAWARNINGs in a future B2C Commerce version (for example, because an element was deprecated or rules updated).
