Migration to S/4 - extension of material number field MATNR


Hello experts,

When migrating to S/4HANA an option to keep the material number at 18 characters or extending the material number field to 40 characters exists. I'm looking for lessons learned or side effects of keeping the material number field at 18. Has anyone migrated without extending the field and then later regretted not doing so.

Any pros or cons related to the extending or not would be appreciated. Interface problems or any collateral impacts.

Warm regards,
