Long Material Number in SAP Fiori Apps (Transactional Apps)
The standard material number allows a maximum length of 18 characters. If this length is not sufficient, the long material number can be activated in the back-end system to allow a maximum length of 40 characters.
Some SAP Fiori apps are enabled to display the long material number (MATNR_EXTERNAL
) instead of the standard material number (MATRN
). If the long material number has been activated in the back-end system, the enabled SAP Fiori apps automatically display the long material number.
