From a procurement point of view, there aren’t many changes in the material master. The most significant one is the field length for the material number (MATNR). In SAP ERP, the Material Number field length was set to 18 characters by default.
In SAP S/4 HANA, though, the Material Number field can support a material number with 40 characters.
This provides flexibility to the organizations with material master number selection requirements that could not previously be met due to character limits.
Material Number and Description are of the same field length.
