I'm puzzled and looking for some ideas on how this might occur.
In doing EOM reports I noticed these details:
05/23/08 G-60 048         60861  B44               2.00         0.0000       82.7200      -82.7200
05/23/08 G-60 048         60861  B44               2.00         0.0000       82.7200      -82.7200
05/23/08 G-60 048         60861  B44               2.00         0.0000       82.7200      -82.7200
05/23/08 G-60 048         60861  B44               2.00         0.0000       82.7200      -82.7200
                                   Item Class: SHT    Total             0.0000     330.8800    -330.8800
 
IN-E reflects the same entries.
after investigating invoice 60861 - it was in fact for just 2 G-60 048 for a total of about $100.
This part is Lot controlled.  
 
I have tried several release scenarios using an offline system with backup data prior to the real release that caused these entries.  Neither I nor the office staff that did the real release can reproduce these results.
 
I am trying to avoid our CPA questioning the confidence of the data.

IN-E says that all 4 transactions are S type.
LC-D has the correct lot number on all 4 entries.
No reversing entries.
 
Re: INVTXN I guess I should have said I tried various release/invoice/post senarios.  Interestingly the timestamps look something like this:
 
G-60 048   USER1   2:06:26
G-60 048   USER1   2:06:26
G-60 048   USER1   2:06:26
G-60 048   USER1   2:06:27
 
these seem petty quick for a human triggered event
 
I figured there was something odd that went on when the system asked for the lot number but can't come up with what.

G/L is fine.  Any suggestions for the cleanest fix? We'll just watch future L/C transactions and assume this one was a fluke.
