smallest unit

[richardevers2002]

Got this question in AB3. Could someone help me with this problem:

A unit of type X must be smaller than every other instance of a unit
of type Y. For example:

Unit Y1 = 5 models
Unit Y2 = 10 models
Unit Y3 = 12 models
Then Unit X must be 5 models of smaller.

How can I implement this in ABv3?

Greetings,

You can't enforce this as a fixed behavior, but you can definitely handle this as a validated behavior. First, you'll need to write a hidden statcalc that determines the smallest size unit of type Y. This can be done by having the Test expression only apply to units of type Y and then having the Tally expression update the value to the model count of the unit only if it's smaller than the previous value. Just make sure that you specify a large initial value as the starting value for the statcalc! Once that's done, it's easy to write a rule with "unit" scope that has an explicit "targetid" of unit X. This rule just verifies that the model count of unit X is not larger than the value from the statcalc.

Hope this helps,
Rob

Thanx. I solved the smallest unit problem too.


Did this:

Made a statcalc rule with entity scope. (S1_SmUn)
----------------
Value is 999 to start with.

TEST expression: Tested on a unit with TAG: S1_help.Y

TALLY expression:
if (@value > entity.count[model]) then
@value = entity.count[model]
endif
---------------

Then made a new rule: (S1_SmUn)
--------------
again entity scope.

TEST expression: unit with TAG: S1_help.X

SCRIPT:
var A as number
A = statcalc[S1_SmUn]
if (A = 999) then
@valid=0
else
if (entity.count[model] < A) then
@valid=1
else
@valid=0
endif
endif

--> where the first if-then looks of there any X unit in the roster at all. The second if-then looks if the Y unit is the smaller than the return value of statcalc.
