Solution to Material Number Errors in SAP System

[CapperMorningCoola]

When executing transaction code MM01 to create material master data, the system displays an error message 'Material number already exists', but I am confident that this is a new material. How can I solve this problem?

Hi,

Have you check material number in MARA table? or in MM60, IH09?
