In Fashion and Retail industry articles can be measured using different standards or scales in different countries or geographical regions. it is very common to have same physical size called by different scales in different countries. This is the reason we have US Size, UK size, etc printed in Shoes. For example, in Men's footwear UK size 9 is called as US size 10. Therefore, both sizes are stated in the footwear.
In order to cater this business requirement; S4 Fashion Verticals has come up with Characteristic value conversion solution, where you can convert one Variant value to a different scale based on different parameters. It is possible to define Variant conversion based on below criteria.

  • Article – Material Conversion ID

  • Customer / Vendor ID (From customer master)

  • User Parameter Profile - FSH_SPC_USR

  • Item Based Conversion

Characteristic Conversion Usage

In S4 HANA Fashion for Generic articles variant articles are created to have different characteristics of material like Size and color. Size variants will be read differently by different geographical region. In S4 HANA variant articles represents different line items in PO and size conversion is available at header level in SAP AFS it was at schedule line level. Each item shows characteristic details as per the conversion selected or applied.

When we enter a generic article in application documents such as a purchase or sales order, the system displays a variant matrix and prompts you to enter quantities for the variants of the generic article. The system displays the characteristic values for each of the variants and the quantities assigned to them in the Item Overview screen. You can only view a maximum of three characteristics for the variants of the generic article.

For successful characteristic value conversion to take place, we have to first create a conversion logic. This conversion logic defines when the conversion has to take place and how the system converts each individual value with a specific conversion type based on certain rules

  • Article

In the article master, we must maintain the Material Conversion ID to associate a conversion ID with an article.

  • Business Partner ID

We have to maintain Customer Supplier  ID for the vendor role in business partner on the Supplier: Retail Attributes tab for the Purchase  Organization

We have to maintain Customer Supplier  ID for the customer role in business partner on the Additional Data tab for the Sales Org. and Distr. Channel.

  • User Parameter Profile

We have to maintain a conversion checkbox for the ID FSH_SC_USR user parameter in the Parameters tab for the user.

  • Item-Based Conversion

The Item Overview tab can have more than one item. Multiple variant-creating characteristics can be associated with an article. Hence, after applying characteristic value conversion on such articles, the system updates the characteristic value 1, characteristic value 2, and characteristic value 3 with the converted values.

Characteristic value conversion is available in documents. You can use the characteristic value  conversion button to convert the characteristic value of articles in the documents without selecting an item.

To have item based conversion in transaction document , we have to maintain in User parameter profile , parameter ID - FSH_SC_NO_AUTO_CONV= X , if Blank then it will be document based conversion.


Activate business function switch - ISR_RETAIL_CHAR_VALUE_SFWS in ISR_RETAILSYSTEM.

System Setup: Configuration

As a part of system setup we have to create some master data and also some configuration as below

Create Characteristics for size and color variants

From the SAP Retailing menu, choose Master Data-->Classification System, Retail--> Characteristic or Use transaction Code CT04

During Characteristic creation

  • Assign Functional Module WRF_CHECK_CHAR_VAL in the Values tab for the characteristic.

  • Maintain Class Type 300 for both characteristic in tab Restrict

We have created 2 below characteristic

  • Characteristic For Size SZ_01

  • Characteristic For Color CL_01

                                        Characteristic details with Functional Module

Create Class

From the SAP Retailing menu, choose Master Data-->Classification System, Retail-->Class or Transaction Code CL01

Here  assign both Characteristic to class type 300

                                        Class details

                                     Characteristic assignment to Class

Maintain Characteristic Type

To Maintain Characteristic types use transaction code  WRFCHVALTYPE to designate the Characteristic Type of each Characteristic

                                      Assign Characteristic to Characteristic Type


System Configuration

Enable system to Characteristic conversion

We have to set Enable Char. Value Conversion in the Customizing activity under Logistics General--> Basic Data Retail-->General Control, Retail Master Data

                                            Value Conversion activation


Define Conversion Types

We have to define a conversion type in the Customizing activity screen under Logistics-General-->Fashion Management -->Cross-Applications--> Characteristic Value Conversion-->Define Conversion Types

Define Conversion Indicator and assignment

We have to defined a conversion indicator in the Customizing activity  under   Logistics – General--> Fashion Management--> Cross-Applications--> Characteristic Value Conversion--> Control Conversion Type Determination.

Here you can specify whether each conversion ID is a material indicator (M) or a business partner indicator (V)

                                        Conversion Indicator and Type assignment

Assignment will help which conversion types can be used depending on the combination of the material, customer/vendor, and user indicators.

Using the sequence number you can define several conversion options for the same combination of indicators and specify one option as the default using the sequence number 0.

The system uses the following sequence during the search

Sequence Material ID Cust./Vendor ID User ID
1 x x x
2 x x -
3 - x x
4 - x -
5 x - x
6 x - -
7 - - x
8 - - -

The combination of indicators with the number 0 is always the default value. The system automatically uses the default conversion types in Fashion Management. This means that you have to manually select non default conversion types to see the values with these conversion types

Characteristic Conversion

To maintain Characteristic Conversion value use transaction WRFCHVAL-Edit Characteristic Value

Variant details

                                        Basic Variant Details

Variant Conversion details for each conversion Type

                                          Basic variant to different conversion type variants details

System Testing

Create Generic article with Variants.

                                             Article with Variant details

Create Transactional Document like Purchase Order and check conversion logic

When we create Purchase order initially system applies base values if Material, Vendor and User ID is not maintained any conversion type. If we want to see different conversion we have to select from PO header conversion type depending on geography

                                      Purchase order with Base characteristic values

We can convert Base value to different conversion ID by selecting from Purchase header as per the maintenance. Even we can default this by User profile parameter.

                                         UK Conversion

                                     US Conversion


By using Characteristic Value conversion business can convert and see variants or size details in different scale based on different parameters. Conversion can be seen in all transactional like PO, PR,  SO, delivery documents also in inventory reports.
