The default "Numeric" serial number is decided by looking up the table MASE. The system stores the last serial number for the material in this table.

When talk about serial no. of any device then we have two things :

External No. range


Internal No. range

If internal no. range has been selected for the device serial no. then whenever you create a new device then a new no. will be allocated to that device based on the no. range you have selected for internal no. range.

If you have chosen external no. range then you need to specify the device no.

For no. range please check 'Define Number Ranges for Logical Numbers of Devices' in img activities.

As Hari has described the table MASE shows the Last numerical material serial number assigned to a material.

Thanks and Regards
