Internal Order Number Generation.

Dear Gurus,

The internal numbers generated in Ko01 are in the number range 71000 to 71999 for the order types ZAMC Z01 etc, but when i am generating the internal numbers, the numbers are being generated as 71001, 71002, 71010, 71020 etc, ie the number increment is not +1 ie it is random, kindly advise why this could be happening.

Thanks,

Anand
