|   | Exceptions in unit effectivityAn exception in unit effectivity is the definition of a
		deviation that applies to a unit effective item. An exception indicates, for
		example, whether a specific BOM line or a specific routing operation is used
		for an effectivity unit. Exceptions are often created as a result of customer
		requirements, or technology upgrades. An exception is defined for an object. The exception indicates
		  whether the object is valid or invalid. The objects for which you can define
		  exceptions in LN are: - Engineering BOM lines
 - Production BOM lines
 - Routings
 - Routing operations
 - Sources of supply strategies
 - Item – supplier data
 
 For example, if you define an exception for a BOM line, it means
		that the BOM line is valid or invalid (dependent on the setting of the Valid
		check box) for an item with a specific effectivity unit. In case you define an
		exception for item – supplier data, it means that a specific purchase business
		partner is used to supply components for a specific unit effective
		item. An exception is on the one hand linked to an object and on the
		other hand to an effectivity unit, or to a requirement as well as an
		effectivity unit: Check box settings for objects For every object, always two check boxes are present with
			 regard to exceptions: - Exceptions Present check box. If this check box is
			 selected, one or more exceptions are defined for the object.
 - Standard Configuration check box. If this check box
			 is selected, the object is part of an item’s standard configuration. The costs
			 for the object are included in the standard cost. If the Standard Configuration check box is cleared, the
			 object is not part of an item’s standard configuration. The costs for the
			 object are not included in the standard cost. The Standard Configuration check box in combination with
			 the setting of the Valid check box in the Exceptions (tcuef0105m000) session indicates whether an object is used for a
			 specific effectivity unit. 
- If the Standard Configuration check box is selected, and the Valid check box is cleared for an exception linked to
				  the object, the object will be omitted for a specific effectivity unit or
				  requirement.
 - If the Standard Configuration check box is cleared, and the Valid check box is selected for an exception linked
				  to the object, the object will be added for a specific effectivity unit or
				  requirement.
