In ‘Define Output Format of Material Numbers’ SSCUI, for field ‘Material No. Length’, the value help shows “Possible length of material number is 1 to 40”. However, in S/4HANA cloud the maximum material number length that can be maintained is 18. Hence, if the user tries to maintain a material number length that exceeds 18 in this field, the application generates an error message.
In S/4HANA, the user cannot maintain the Material Number length more than 18. Hence, you must enter a number ranging from 1 to 18 in the field ‘Material No. Length’.
Documentation for the same is also available for the customer. Kindly ignore the value help information.
