Production Orders and decimal places

[Podgetheelder]

Any suggestions please on a work around for a current issue where Bill of Material child items are as below:
Planned Qty Item
200,000 A
1 B
1 C
1 D


Because items B,C,D are all single units the Base qty can't be show as under Administration Initialization set up the Item Qty decimal places is set to 3. An error message appears stating that the base qty is required! without changing the decimal places to 5 (which will be irreversible, and will have an impact else where on the system) is there any other work around.

Suggestions on a post card please
