MIR7: Document number gaps when delete parked invoice

[xuarchy]

Dear All，

When I use T-code MIR7 to park PO invoice，system can take up one document number, if I delete the parked invoice,then document number gaps.

I use SNRO to switch off  the buffering ,the object is "re_beleg",but it doesn't work.

An external number  assignment isn't setted for our document number.

who can tell me how to fixed this?

What is the problem if a number is lost, it was taken from the range and you deleted it, the number will not be added back to the range.

If you are legally required to have a sequential numbering then you should probably not allow parking and deleting.
