Null Value in Dependency Calculation

[becca656]

We have a business scenario which requires us to include the variable of null (not zero, but blank) as a dependency in our classification characteristic

dependency.

That is, we have the following:

$SELF.variable A=

330

if variable B= '10'

AND (variable C = ????)

AND ((variable D LT 50

AND

Variable E LT 6) OR

Variable E LT 160)

Variable C needs to be a

null value for the dependency. We have tried two single quotes to represent blank and two double quotes to represent blank (e.g., ""), and tried the same with a space in between the quotes but we are getting syntax errors (E28024) with this entry.

Any ideas how to manage this scenario?

Becca Hallock,

its seems that variable C is not at all needed to be add into condition , as you must have created this characterstic with no value or with certain values , but " Blank " is not at all a option while maintaining it.

so if you requirement is , configuration should have all other excluding variable C with a value, you can use condtion like NOT SPECIFIED variable C.

If you have created variable C, without any possible value , its not at all needed in the condition.

please think over it and revert back.

Hope it will help you.

Thanks

You can use the syntax NOT SPECIFIED FOO to check whether a characteristic FOO has no assigned values. Note, however, that this syntax cannot be used in Constraints.
