We have a business scenario where we are selling in one unit of measure and delivery in another. However, the conversion rate between the two can be different. Here is a scenario.

1. We sell 10 units of item 1
2. We make a partial delivery for this item and the conversion is 2 units of item 1 for 1 unit of item 2.
3. We want to make another partial delivery, but the ratio is now 3 units of item 1 for 1 unit of item 2. However, the system uses the first conversion and does not allow us to change.

Anyone know of a way to handle such a scenario? The reason for the different in conversion is due to testing. Some of the components are bad, therefore, we cannot charge our customers. And all the units comes bundle togather. Therefore, we can only charge by the yield.

You can use Proof of Delivery (POD) functionality.

Using POD you will allow Billing quantity to be different with Goods Issue quantity.

For example: GI quantity is 10 unit, but your customer will only pay for 7 unit, then you can create POD for 7 unit. So that billing quantity is 7 unit.

If the issue is not in the proof of delivery, it's in the delivery itself. For example, my handling and manufacturing unit of measure is unit A, and my selling unit is unit B. For every unit A, there's a different conversion due to failures and yields. Therefore, when a make the first delivery, the system will let me issue delivery in unit A and I can change the conversion rate. However, when I make the second delivery, the conversion rate is set based on the first delivery and I can't change it even though the rate could be different.

If this is the case, then you might consider using batches and batch specific units of measure.
