SAP S/4HANA Cloud currently does not support material number with more than 18 characters length. This is mentioned in the Configuration Help of the SSCUI

This maximum length cannot be exceeded through customizing ( SSCUI or through Expert Configuration )

With SAP S/4HANA On Premise since release 1511 material numbers of up to 40 characters is available and Supported but there is no plans to add this functionality to the scope of S/4HANA Cloud.

In S/4HANA Cloud the maximum length 18 ( 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.

Please use a Material Number or Old Material Number less then length of 18

Please use the Continous Influence Program ( https://www.sap.com/about/customer-involvement/influence-adopt.sap-continuous-influence.html ) to have the functionality enhanced to allow material number length greater than 18

For the latest updates on the planned function capabilities, please refer to the SAP S/4HANA Cloud roadmap. Available under https://www.sap.com/roadmaps, the roadmap is updated quarterly.
