Purchase Requistion (ME51N) : BADI ME_REQ_POSTED

Hi,

I have used ME_REQ_POSTED-post(Method) Badi to check custom consistency in ME51N. If there is any error the badi throws the Message and returns to t-code : using leave to transaction sy-tcode which is working fine, but the problem is that even the creation of the PR is manually stopped the PR number is generated and not saved(say: 8000012). Next time when I am creating a new PR with the same consisentcy check and if it gets through a new number is generated with (say 8000013) but not with (8000012).If this case araises there will be problem with number range allocation each and every time they get exhausted?

Kindly post the solution if any one has ever faced.....

Thanks in advance for the help.

with regards,

krishna Mukthineni.
