Number range does not exist

Hi Friends,

I am facing the problem in Number generation function.

e.g. NUMBER_GET_NEXT,

CALL FUNCTION 'NUMBER_GET_NEXT'

EXPORTING

nr_range_nr = '01'

object = 'ZGPNO'

IMPORTING

number = gpno .

In that the error message is Number range '01' does not

exist .

But in one client its executing like Developer client (the ZGPNO object is avail with number range) but in other clients (object avail) its not working even though it gets Transported.

Please help me to solve this problem.

Thanks in advance

Regards
