On : 12.1.3 version, Incremental Backflushing

On doing Incremental Backflush system doesn't round off correctly for Ingredient qty up to 5 dec places

We have few Finished Goods where the ingredients quantities can go up to 5 decimal places.
When we do a partial completion of these FG's we see that the standard Incremental backflush doesn't round these ingredients correctly.

For example, if the WIP Plan Qty and reserved qty is 0.16667 and an IB is done for 50%, a WIP Issue is created for 0.08334 and the reserved qty goes to 0.08333. Then when a second IB is done for 50%, Material Exceptions is displayed because the system tries to consume an additional 0.08334, but only 0.08333 is available.

A second scenario involving a quantity of .00011 was also reported and fixed.

Expect to get a correct rounding in order to avoid exception messages

The issue can be reproduced at will with the following steps:

1.In OPM batch: have ingredient with the required quantity on the batch as 0.16667 kg reserved on the batch and Product Qty of 10 ea.
2. Do a Partial Incremental backflush on the Product Completion of say 5 ea. the system would backflush the ingredient as 0.08334 kg and 0.08333 as
reserved qty.
3. Now when trying to do a backflush of remaining 5 ea. System throws an exception of 0.00001 kg.

The issue has the following business impact:
Due to this issue, users have trouble performing Partial Incremental backflush
