Bill-of-Material Maintenance

  • Updated
The Bill of Material(BOM) Maintenance screen displays all items that are a part of an assembly of another item that is maintained in GAINS.  Items that are a part of another item are called “components” in GAINS, and items that are comprised of one or more components are called “kits.”  The Bill of Material maintenance shows the relationship between the kit and the components.

BOM Tab

The main BOM tab has two sub-tabs: the “Bill of Material” tab displays all of the components that make up one kit.  The “Kits Where Used View” tab displays all of the kits that a component is a part of. 

Users can retrieve component items on the “Where Used View.”  After a component has been retrieved, clicking on the “Bill of Material” tab will display all components that are a part of the highlighted kit.  The user also has the option of viewing all of the components of the record that has been retrieved in the SKUL Header.  If the user retrieves from the “Bill of Material” tab and clicks on the “Where Used View”, all kit items that the highlighted component is a part of are displayed

Adding New Relationships

New BOM Relationships can be added to the screen by clicking on the “Add New Row” icon in the toolbar when on the “Bill of Material” tab.  The components that are in the kit item’s bill of material should be entered by typing in the first few characters in the pop-up window and selecting the proper components from the list that is generated. Users can also add Multiple BOM Relationships by selecting the "Add Multiple BOM Relationships" icon in the top left.

Description of fields on the BOM tab

Field Description
Distribution Level Distribution level of the listed part.  Components must have smaller distribution level values than kits 
Kit Item/Comp Item Kit Item number is displayed on the Where Used View tab, Component Item number is displayed on the Bill of Material tab 
Kit Loc/Comp Loc Kit location number is displayed on the Where Used View tab, Component location number is displayed on the Bill of Material tab
Description Description of the SKUL 
Quantity Number of components that are required to assemble one kit, or number of kits that can be created from one component 
Yield Pct Yield Percentage is the error margin for creating a component, based on the prior history of the item
Start Date Date that the bill of material relationship becomes active 
End Date Date that the bill of material relationship becomes inactive 

 

P-BOM Tab

In addition to the replenishment bill of material system described above, GAINS also offers a “planning bill of material” for scenarios where:

  • The components need a demand forecast instead of just replenishments driven by the kit’s forecast; and/or
  • The components are optional to the kit and the usage and frequency need to be calculated within GAINS. 

For example, many highly configured products and complex repair jobs are planned according to generic top-level configurations or jobs.  A planning BOM offers both the top-level forecast and also determines forecasts for associated components.  In the second scenario where the BOM usage for optional components cannot be easily obtained, GAINS can use existing demand transaction data to determine the frequency and usage for each kit-component combination. 

 Example: Leading entertainment equipment manufacturer uses GAINS planning BOM to:

  • Forecast kit-level demand for various bowling alley configurations
  • Derive PBOM relationships, frequency and usage based on demand transactions
  • Generate forecast for individual components that feed into kit

Input Data for Planning BOM’s

Relationships are defined by the links between PBOM Kits and the Components which go into each Kit

Three methods of interfacing P-BOM relationships into GAINS:

    1. Auto creation based on new built-to-order kit data in demand transactions
    2. Direct load via input data file
    3. Manual data entry via P-BOM screen
      • Users may create and maintain P-BOM records within this screen, if the records are not being interfaced from another system. 
 

Description of Fields on the P-BOM Tab

Field Description
Kit Item No Item requiring component parts
Kit Loc No Location of the item requiring component parts
Kit Description Description of the kit
Comp Item Component item used in kit listed above, possibly multiple per kit
Comp Loc Location of the item used in the kit above
Frequency Percentage of kit demand driving component demand.  Calculated by GAINS based on demand transactions, or input through interface file, or maintained within this screen
Freq Override Overrides calculated frequency value. -1.0 indicates no override (i.e. use GAINS calculated value) 
Usage Average quantity of component demand per unit of kit demand.  Calculated by GAINS based on demand transactions, or input through interface file, or maintained within this screen 
Usage Override Overrides calculated usage value. -1.0 indicates no override (i.e. use GAINS calculated value)
Comp Description Description of the component
