What’s Merchandise Category in SAP ?

Merchandise categories enable the user to classify and structure all aspects of the merchandise in their enterprise. In doing so, each article is assigned to a specific merchandise category. This assignment is valid throughout the enterprise.

Merchandise categories can be assigned to stores and store departments. You can also group merchandise categories into hierarchies. A successfully implemented merchandise category hierarchy is an essential tool for efficient merchandise category management.

The main focus for the management of your merchandise then shifts from individual articles to merchandise groupings. The aim of merchandise category management is the better coordination of various customer considerations at each business location (for example, store), including elements such as variety, price structures and advertising.

Merchandise Category & Hierarchy Quick Tips

How To retrieve Merchandise Category’s Hierarchies of an Article

“Retrieving MCH level is to be done with the following logic:

  • First take the Merchandise category of an Article from MARA table from field MARA-MAKTL.
  • Pass this merchandise category to a function MERCHANDISE_GROUP_HIER_ART_SEL.

This function will return the MCH levels.”

An Alternative way is to use Tables

“If you wish to scale the Hierarchy via tables you will need to do this via the classification structure. SAP Retail uses the class type 026 for the different Hierarchy Levels.

Therefore, starting at the highest level in WGUS use table KLAH and enter the hierarchy number/name in the CLASS field and retrieve the CLINT field value you can then pass this CLINT value to table KSSK and retrieve the assignments.

Your objective is to get the OBJEK entries and pass these values back to the KLAH table field CLINT to retrieve the CLASS field so you can see the number/name value that are displayed in transaction WGUS.”
