|   | To set up unit effectivityTo set up data for unit effectivity, carry out the following
		  steps: - Select the Unit Effectivity check box in the Implemented Software Components (tccom0500m000) details session.
 - Select or clear the Generate Effectivity Unit during Demand Entry check
		  box in the Unit Effectivity Parameters (tcuef0500m000) session. 
- If this check box is selected, and also the Unit Effective End Item check box is selected in the Items (tcibd0501m000) session, an effectivity unit is automatically generated when you create a new sales
				quotation line, sales order line, or sales contract line for an unit effective
				item. Otherwise, you can enter an effectivity unit yourself. The effectivity
				unit can be used for pegging purposes. If desired, you can click Requirements on the order line to select
				requirements to model the item. Unit effectivity is then used as a lean
				configurator. The effectivity unit is linked to a series that is defined in the Default Series field.
 - If the Generate Effectivity Unit during Demand Entry check
				box is cleared, and you create a new sales order line, sales quotation line, or
				sales contract line for an unit effective item, the effectivity unit is by
				default 0 (zero). Only if you click Requirements, an effectivity unit is created, after
				which you can select requirements to model the unit effective item.
 
  - For engineering items, you can use the Unit Effective End Item check box in the Engineering Item (tiedm0110m000) session so that an effectivity unit is automatically generated if you create a new sales
		  quotation line, sales order line, or sales contract line for an unit effective
		  item. If required, you can select the Interchangeable check box.
 Specify business requirement codes and descriptions in the Requirements (tcuef0106m000) session. You use requirements later on to: - Link them to exceptions during the design of, for example,
				a BOM or a routing (series approach).
 - Select them if you enter an effectivity unit in the sales
				order line (sales order approach). This eventually results in production orders
				that use the exceptions defined for the requirements.
 
 For every requirement, you can define an upgrade price. The upgrade prices are part of the
			 effectivity unit's sales price. - If desired, you can define default requirements for end items
		  in the Item - Requirements (tcuef0108m000) session. You can import those
		  default requirements in the Requirement - Effectivity Units (tcuef0107m000) session if an effectivity unit is defined for the end
		  item.
 
 How to continue Now that you have set up unit effectivity, you can use it in the
		way you defined it in step 2. For more information, refer to:    |   |
