OV number skipping and receipt routing problem

 Hi,

This problem is in Oneworld Xe.An OV document numbering series was set to start with 10****** from start of 2010. It has been found that OV numbers are skipping 2-3 numbers suddenly in between. I created 5 Ov's continously on 1 machine with only 1 user active. After 2 Ov's it started skipping the numbers. There is no particular pattern or item found where such cases are happening.

When an OV is done from a receipt routing stage for eg. a PO with 10 lines is selected but stores need to do an ov for only 6 of them, in some cases only the last line goes through fine while other lines do not appear for voucher match. The open qty and open amt fields are not updated properly. Similarly there is no GL entry for the same.
