Inconsistancy in confirmation counter

Hi,

We done partial confirmation for production order.Partial confirmed quantity is 100,100,200,500.

In MB51/co03 GR documents(101 mvt) have posted correctly.

When i tried to view confirmation in co14 disply it is displaying only 3 counters i.e

operation/counter Operation quantity/confirmed yield

1 100

2 200

3 500

But It should be updated in 4 counters,one 100qty is missing.

In AFRU table counters has been updated as

counter qty

1 100

1 100

2 200

3 500

Counter has been update as 1 for both partial confirmation qty so in co14 it is showing only one
