When you enter an alternative item group, you maintain the Priority, Strategy, and Usage probability in a dialog box. Usage probability Material requirements planning (MRP) plans the alternative items according to usage probability.If you use the usage probability to determine the withdrawal posting (strategy 1), the quantities are proposed according to the usage probability. You can change the proposed quantities.An alternative item is only planned if the usage probability is at least 1%. If the usage probability is 0%, a dependent requirement with quantity 0 is generated for the material. It is possible to plan too much for alternative items, because you can enter usage probabilities that add up to more than 100...

Before you maintain alternative items, decide the following points for MRP and withdrawal postings:Do you want to assign the same item number to all alternative items in an alternative item group? Which character string do you want to use to group alternative items together in an alternative item group? What is the usage probability for the individual alternative items in the assembly? What are the priorities of items in an alternative item group? Which strategy do you want to use for withdrawal postings? To maintain alternative item data:Go to the Material Item Overview. You will find it easier to use the same item number for all the items in an alternative group. Change the item num...
In material requirements planning (MRP), the discontinuation data in the material master record transfers dependent requirements for a material component that is no longer in stock (in sufficient quantities) to a follow-up material. You can also specify a follow-up material for an item in a BOM. The data for this is maintained as Discontinuation data. The follow-up item specified in the BOM overrides any follow-up material maintained in the material master record. Multiple levels of discontinuation data are not supported. Once a material master record (MRP data) has discontinuation indicator 1 (simple/parallel discontinuation) and a follow-up material, you can no longer enter the material as a follow-up material in a BO...

The planned order creates an independent requirement for the assembly with an order start date and an order finish date.The order start date of the superior assembly is automatically the requirements date for the resulting dependent requirements (material requirements for subordinate components). The system uses a number of factors (for example, in-house production time, processing time, and interoperation time) to calculate the start date of the planned order for procuring components.You can maintain the following material requirements planning (MRP) data for a BOM item:Entering a Lead-Time Offset Distribution Key Special Procurement Key Explosion Types See also: Maintaining MRP Data PP

In this field, you can enter the distribution key for dividing up dependent requirements or reservations for this component over time. In Customizing for Production, you define distribution functions by choosing Repetitive manufacturing ® Planning ® Distribution ® Define function.If you enter a distribution function for a component, portions of the dependent requirement are distributed over the runtime of the planned or production order in accordance with the distribution function.This means that dependent requirements are not available in full on the order start date. Instead, they are brought into the production process continuously between the order start date and the order finish date.The last portion of the dependent requirement must be available at the latest on the...
This indicator determines the special procurement type of a material which is either procured externally or produced in-house.The system determines the special procurement key from the Procurement type and Special procurement fields in the material master record (Detail Screen: MRP 1) and displays the value if the BOM is only allocated to one plant.The system only displays the values that are relevant to the explosion type for a BOM item.Phantom assembly Direct production (collective order) Phantom assembly A phantom assembly is only required for engineering/design. It does not occur physically in the course of production. In the planning run, the component materials of the assembly transfer requirements. The header material of the assembly is not...
The explosion type determines the procedure that is used to explode the BOM in order to determine dependent requirements.You can also use this key to control the explosion of the BOM for the planning run.This allows you, for example, to define the explosion of assemblies with a special procurement key according to various criteria. Indicators that Control BOM Explosion In Customizing for Production, you define whether the following system activities take place by choosing Bill of Material ® Item Data ® Define explosion types:Switching Off the Phantom Assembly Switching Off Planning Switching Off Direct Production (Collective Order) Long-Term Planning Individual/C...
Standard Explosion for Phantom Assembly If the material master record of a BOM header material contains the special procurement key Phantom assembly (value 50 in the standard R/3 System), dependent requirements are generated for components of the phantom assembly, and planned orders or purchase requisitions are created only for these components. In the material master of material B, Phantom assembly is set in the Special procurement field.Material B is a material component in a BOM and has item number 0010. It also has a BOM of its own, containing components B1 and B2.In the standard system, dependent requirements are generated for components B1 and B2 when the BOM is exploded in MRP.The following graphic shows how a...
The Planning off indicator is relevant to multi-level production with assemblies that are not produced in advance. If the production time is long in relation to the usual delivery time, the replenishment lead time must be kept short. For this reason, the components and assemblies of the final product are produced in advance, but final assembly does not take place until a sales order is received (for example, in the case of cost-intensive materials or operations). The replenishment lead time for some components, such as purchased parts, can be very short. You do not need to plan these components. Demand management supports the following sales-order-based planning and production strategies, which are oriented toward ma...
Components with this indicator are produced directly for the superior assembly in the R/3 System. The planned order produced for the component is linked to the superior assembly. If components are produced directly for the superior assembly, dependent requirements are selected accordingly. The system generates a special planning segment under the heading Direct production.You can define the explosion type so that Collective orders are switched off for the component.In the MRP data of the material master record for the component, enter dependent requirements indicator 2 (collective requirements only).Maintaining MRP Data PP Bills of Material General .....
Long-term planning allows you to simulate materials planning, in parallel to operational materials planning, across all low-level codes. This means that you can use the current bills of material to determine the effects of a planned production program on the material requirements and the capacity load.In the standard R/3 System, long-term planning affects all low-level codes.However, if the BOM is very large, long-term planning can affect system performance. For this reason, you can switch off long-term planning for a low-level code if it is no longer required.Maintaining MRP Data PP Bills of Material General ...Individual/Collective Requirements for De...
This indicator controls whether individual or collective customer requirements planning is allowed for dependent requirements.If you define individual requirements for explosion, dependent requirements for a component are shown individually on the superior low-level code.If you define collective requirements for explosion, required quantities for the material are summarized independently of the sales order.Maintaining MRP Data PP Bills of Material General ...Individual/Collective Requirements for Dependent R...Long-Term Planning PP Bills of Material General It...Switching Off Direct Production (Collective Order)...Switching Off Planning PP Bills of Material Genera...Switching Off the Phantom Assembly PP Bills of Mat...Explosion Types PP Bills of Ma...

You display and enter the data for discontinuation in a dialog box.Discontinuation indicator Discontinuation group Follow-up group Discontinuation indicator for discontinued material If this indicator is set, the material is defined as 'to be discontinued'. The material is then discontinued in MRP. MRP transfers dependent requirements that are no longer covered by stock of this material to the follow-up material.You maintain this indicator in the MRP data of the material master record. If the bill of material is assigned to several plants, you see the discontinuation indicator for the initial plant. Discontinuation group This freely-definable character string groups together related discontinued items in a BOM....
A BOM is recursive if the product contains a component with the same object number as the superior assembly. This is often due to input errors, but in individual cases it may be intentional. A component has the same material number as a higher-level product. In paint production, a residual quantity of the paint to be produced is used as a component. The figure below shows the repeated explosion of an object within an explosion path (recursiveness). Recursiveness check within a BOM group The recursiveness check includes all BOMs in a BOM group. For example, the system finds recursiveness in a variant BOM, even if an individual variant is not recursive. A variant BOM has 2 variants: The first variant for material A...
Many companies have only one universally applicable BOM structure for all areas of their company. This structure usually takes the form of complete single-level BOMs, created in the design department, and used in both material management and the assembly workshop.The R/3 System allows you to maintain individual BOMs for any area of your company. These BOMs are maintained independently of each other and are assigned different internal BOM numbers. In this way, each area is only dealing with the specific data it requires.In Customizing for Production, define individual BOM usages for the different areas within your company by choosing Basic data ® Bill of Material ® General data ® BOM usage ® Define BOM usages.You can define BOM usages for the following scenarios:You ma...
If you maintain separate BOMs for a product in different areas of your company, you can use BOM reporting functions to obtain information that is directly relevant to your requirements.The design BOM includes all the components of the product and their technical data from the design point of view. This BOM is generally not linked to any order.The production BOM includes all the items required from the production and assembly point of view. To assemble a product, you only require items that are relevant to production, which contain process data.The costing BOM describes the product structure and is used to automatically determine the costs of the materials required for a product. Items that are not relevant to costing are not included in the costing BOM. Each area (for example, productio...
By defining the BOM usage (Customizing for Bills of material, step Define BOM usages), each company determines which item statuses can and cannot be set.The item status covers a range of indicators that can be entered for BOM items, such as relevant to engineering, relevant to production, relevant to costing, and so on. These item status indicators control:Processing of the BOM in related application areas. The indicators define whether further processing is required, allowed, or not allowed. If processing in an application areas is supported, you can maintain application-specific data for the items. For example, only items that are relevant to production are copied to a production order. The selection of items for BOM explosion See also: Restri...
