PP - Controlling data for your Bill of Materials

PP - Controlling data for your Bill of MaterialsYou define the default values for BOM in OS28. - Based quantity - BOM Status - Size Unit - Var-size item unit You control the Material type allowed for the BOM header in transaction OS24. In transaction OS27, you define the central settings for your BOM management system.  This  are one-time settings for BOM management, which should not be change after production. Low date When you create or process BOMs, the default date is the date defined in your system as the  earliest processing date (01/01/1900 in the standard system). BOM validity maintenance Tick if want the user to specify a valid-from date when maintaining BOMs. If not tick the BOM created as of the current date or the system low date (1/1/1990). EC management active Tick if you want to make historical changes to BOMs with reference to a change number.  (This means that the status of the BOM both before and after the change is stored in  the system.)  In this step, you only specify whether engineering change management can be  used for maintaining bills of material. In transaction OS25, Configure history requirement  for BOMs, you define whether you want to make the use of engineering change management a  requirement in certain cases. Hist. reqmt variant Use this indicator to control when history requirement applies to new variants or  alternatives in a BOM group.   Sub-item documentn You use the Sub-item documentation indicator to define whether changes to sub-items are  documented.  Header Create BOM header with parameter validity TECHINCAL TYPE Mult. BOM inactive Tick if no multiple BOMs can be maintained in this R/3 system. Variant BOM inactive Tick if no variant BOMs can be maintained in this R/3 system BILL OF MATERIAL ITEM BOM item explosion type If you create a BOM item with reference to a change number and change the valid-from date  (in the change header or alternative date), then this can change the sequence of validity  periods of a BOM item. The indicator BOM item explosion type specifies whether and according to what rules,  the system determines a unique change status, when you display, evaluate or change a BOM to  a date in the overlap period. Description variable-sized item This indicator controls which text is displayed in BOM processing for a variable-sized item. Repeated effectivity via external item ID This indicator ensures that an item that already exists under an external item ID can be used. General settings Unit 'piece' In the standard system, this field contains a unit of measure for "piece". You can change  this unit. This unit is the base unit of measure (BOM header) or the component unit of  measure. Base unit of measure for: Equipment BOM Functional location BOM Document structure Standard BOM Component unit of measure for: Text item Document item Non-stock item without material master record CAD active If you want to maintain BOMs from a CAD system, set this indicator. This activates an  additional field in the BOM header and BOM item, which tells you whether the BOM header or  BOM item was maintained from a CAD system. If you deactivate engineering change management, changes to bills of material are not  recorded. The modification parameters defined here apply to all BOM categories. The following settings are made in the standard R/3 System: 1.  Validity date maintenance and engineering change management are active. 2.  The current system date is the default valid-from date. 3.  CAD is active. 4.  Explosion type for BOM item: blank.
