1.I have one customer exit , ZXV56U12(include),which is in Enhance ment V56UNUMB.
2.Here I can give number range or directly number , which comes for shipment.
3.I am giving the number , by executing functionmodule : check the beloe code which is written in Exit.
->for e_numki , i am giving one number range from which it givces u the next number to be allocated.
->this the below function module will give u the number w_number.
-> i have to check the whether with this number , there is invoice exists,If it exists then again i have to go for the next number
,That's y i kept in the loop.Please look at the code u will understand.
->it is working fine.;But it is missing so many numbers in the specified range .
->it has to miss only if there is invoice exists with that number.But even though invoice does not exists,it is missing some numbers some times.
->what might be the reason for this?
CLEAR : w_number,w_vbeln.
