Article Units

Frequency:

Article unit master data changes are required to be sent in near real-time. Any change to an interface field in the external system should trigger the interface.

Expected data:

The external system is expected to report at least two levels of article units:

• Base unit (e.g., piece, kg)
• Warehouse/distribution unit (e.g., block, crate, box, distribution package)
• Layer and pallet levels are optional.

Countable articles: use piece as the base unit.

Weight articles (average or catch measure): use kg as the base unit.

For weight articles (average or catch measure), the coefficient to the warehouse/distribution unit should be equal to 1.

Technical:

The DSWMS unit hierarchy should be mapped to the external system.

If an article unit record does not exist in DSWMS, the record will be created.

If an article unit record already exists in DSWMS, the existing record will be updated with the new data.

unit_id must be a unit of measure configured for your client in DSWMS. A unit with an unknown unit_id is ignored without an error, and the remaining units of the article are still imported.

Send at most one unit per article_unit_type_id. If the same unit type appears more than once for an article, only the first entry is imported.

Units that are not included in a request are left unchanged. This interface never deletes article units.
