how to delete some wrong batch numbers and changing the first half of a serial batch number

[Former Member]

Hi,

I use SAP Business One (version 9.2).

Some of the batch numbers were entered wrongly but now I was wondering how to delete them because they keep on coming back (they are sometimes seen as the reference while they are not).

Furthermore I was wondering how to change the first half of a batch number: now we have 18401000 but I want to change that to 19401000 (so the 18 has to change into 19).
