Symptom
- When changing or updating product numbers, the system raises error "Material number must not be longer than 18".
- Error "The length of the old material number must not exceed 18 characters" appears when updating or saving a product through Create Material app, Change Material app, Migration Cockpit app or API API_PRODUCT_SRV.
Environment
SAP S/4HANA Cloud Public Edition
Reproducing the Issue
- Open SSCUI/Configuration Activity 102320 "Define Output Format of Material Numbers"
- Click on the Configure button
- Input a material number length greater than 18 and save
- Error appears
Cause
The default length of 18 characters (Compatibility Mode) is set to allow for Integration with other systems (through communication scenarios) where material length of more than 18 characters is not possible.
Resolution
The default length of 18 characters is set to allow for integration with other systems where a material length of more than 18 characters is not possible.
When the material number length is set, both the Material Number and Old Material Number fields are set with the same length.
Please note: Once configured, the length of the product number must not be reduced (KBA 3560881).
