Business Add-Ins for the Extension of Archiving

The archiving of SAP Products can be extended using the following Business Add-Ins:

Business Add-In

Method / Use

PRODUCT_ARCHIVE

Using the method CHECK_ARCHIVABLE, you can define your own usage checks for SAP Product.

Using the method ARCHIVE_EXTRA_DATA, you can write additional data per product to the archive file.

Using the method EXPAND_EXTRA_STRUCTURE, you can include additional table structures for the SAP Product in the archiving.

Using the method VERIFY_EXTRA_DATA, you can define your own deletion checks for SAP Product.

COM_PRODUCT_DELETE

Using the method DELETE_EXTRA_DATA, you can define other data that is to be deleted when deleting a product and that does not directly belong to product master. However, you do not use this BAdI to delete the data of customer-defined set types; this is automatically integrated in archiving during generation.

For more information on Business Add-Ins, see the Customizing of the Cross-Application Components under SAP Products ® Enhancements.

Structures for the Archiving Object of the SAP Product

The following structures are used to define the archiving object:

Structures

Structure link Archiving Object

Defines the product archiving framework.

PRODUCT_MD

Archiving information structure

Defines the amount of all those fields that can be indexed that can used in field catalogs and thus in product archives.

For more information, see Structure link Archive Information System.

SAP_PRODUCT_AIS

Structure link Field Catalog

Structure of an archive index that is maintained in the SAP Archiving Information System. A field catalog always belongs to an archiving information structure. An archiving information structure always belongs to an archiving object.

SAP_PRODUCT_MD

Tables for the Archiving Object PRODUCT_MD

The data archived and deleted in the archiving object PRODUCT_MD comes from the following fixed tables. All of the table structures that are to be archived (such as customer-defined set types) are determined when the archiving write program is run:

Tables

Table	Description
COMM_PRODUCT	Product header data
COMM_PRODUCTH	History of the product header data
CRM_JCDO	Change documents for the status object
CRM_JCDS	Change documents for the system /user status
CRM_JEST	Individual status per object
STXB	SAPscript texts: Texts not in SAPscript format
STXH	SAPscript texts: Header
STXL	SAPscript texts: Lines

Additional data for the product (for example, set types and multi-value attributes) are archived and deleted. This data is determined dynamically in the archiving write program.
