Description

Block by Extended Attribute eliminates each decision where the item at the specified source region location does not have an extended attribute that matches the item at the destination region tail location.

Parameters

This function block has the following parameters:


Parameter		Description
Always Evaluate	Hard, Soft or Breakable. This parameter controls what happens when the extension eliminates all available decisions.
	Hard	All decisions will remain eliminated. Note: When all decisions are eliminated the RCO Output Module, `None`, is executed to handle this condition.
	Soft	Roll back any decisions eliminated by this extension.
	Breakable	Roll back any decisions eliminated by this extension that have a danger point value of True (non zero). The routing modules will first use the danger defined for each individual decision; and, if no danger point has been configured for the decision, then the site-wide danger point will be used. If no danger point can be found for a decision, then the decision remains eliminated.
Item Class	All items with matching class will be used.
Location	Number of locations in source regions to scan.
Attribute ID	Name of extended attribute to compare.
Start Character	Starting character of the extended attribute value to be used.
Attribute Length	Specifies the number of characters in the extended attribute value to compare.
End Character	Ending character of the extended attribute value to be used. Enter zero in both the Start Character and Attribute Length fields to use all characters.
