Legacy number in the material master

Dear SAP Guru,

Good day.

We are currently in production support today and we want to understand how a legacy number differs from a material number. As we can see in the material master (Classification View) there is an indicated legacy number there with a corresponding value. Could you further elaborate on how and what is the usage of a legacy number?

Thanks in advance for your help.

Kind regards,

    Basically some clients would be interested to track the SAP material number with referance to the Legacy material number, this data would be uploaded during the Cut-over and data conversion to SAP.

    I would suggest you look at the Functional/Tehnical specification document for the conversion program which was used for uploading the material master data into SAP, that would give you the business reason and the field mapping details.
