Confirm TO Query (ref:L_TO_CONFIRM)

Question

HI Everyone,
I have a query regarding TO confirmation that I'd appreciate some advice on. I implemented a custom RF transaction to confirm TO for putaway using the function module L_TO_CONFIRM. To my mind it's working as it should but my client has reported what they think is an error. Bascially when the TO is created from the goods receipt it's creating entries as follows . e.g
Material  Batch   QTY
1234      ABC     1
1234      ABC    1
Now when the client uses the RF transasction they scan in the details for material batch and quantiy and perform the confirm action. In the example above they enter Quantity as 2 so they expect both lines above to be confirmed. Currently it just confirms one of these lines. My question is this:
Why have two different lines on the TO/GR with the same material and batch instead of just one line with a quantity two ?
and
Can the function module L_TO_CONFIRM handle the above scenario ? 
Any help or advise is greatly appreciated.
Thanks for your time

Answer 1

More or less what J put.  Presumably you've got two TO items as there are two destination bins.  On that basis confirming a quantity of 2 is incorrect if that is against a single TO item.  In fact you should probably have some form of feedback given to the operator to that effect i.e. an 'error' or 'warning' sound and msg as quantity input does not match quantity expected, for your custom RF tx.
You've got two issues:
1. Understand why quantity split over two items and possibly correct settings
2. Consider how to present the information to the operator so the operator understands the expected quantity and is alerted to entry of a quantity that doesn't match.
