Unit of measure conversions..

[Rob Rogerson <rogerson@xxxxxxxxxxxx>]

I wondered if any one else was experiencing the same problem with conversions 
as us.

It is not unusual to have the following situation:
Purchasing unit of measure is dozens.
Stocking unit of measure is eaches.
Issuing unit of measure is 3's(hereby called P3's).

In the parts file (INP35) these units of measures are entered along with their 
conversion factors.
Item     Purchase Unit  Stck->purch  Stock Unit  Issue Unit  Issue->Stock 
PNUM35   PUNT35         SPCF35       SUOM35      ISCF35      ISCF35 
-------  -------------  -----------  ----------  ----------  ------------ 
2135P3   DZ             12.00000     P1          P3          .33333  

This causes the following problem to exist.  If there are 3 eaches in stock 
then how many P3's do we have.
3 * .33333 =   0.99999

JBA usually tracks quantities to 3 or 5 decimal places.  This causes a problem 
because then conversion does not work out to a whole number.  In purchasing, 
where items are normally ordered in dozens but received in eaches, this causes 
major havoc since the receiver always is receiving a whole number yet the 
system is telling him that he must account for a fraction of a whole number.

We have fixed these problems at our sight but since we are upgrading to 3.5 -> 
3.5.1 we will have to fix these problems again.  Is there any one else out 
there with the same issues?  I have tried to convince JBA that if you have 3 
eaches of an item it follows that you have 1 of the item if sold in 3s but JBA 
still contends that the system is correct and really there are only  0.99999 of 
the item.

One of JBA problems I have found is that the software is being designed by 
programmers not business analyst.  What works great for a programmer may not be 
a realist business practice.
