generate alphanumeric serial number with the following BADI / Customer Exit:

Name of Enhancement : IQSM0001

Name of Function Module Exit: EXIT_SAPLIPW1_001

Name of Include : ZXQSMU01

ZXQSMU01:

This user exit can be used to create the serial numbers automatically for material of a production order. Number of serial numbers generated will be equal to the total number of quantity. The purpose behind development of this user exit was to attach prefix
