This function is used to replace a component with another, for one or several BOM codes to select, and for one or several parent products using this component.
The replacement does not mean that a "physical" deletion of the replaced component takes place. It is rather a logical deletion that occurs. The processing modifies the validity end date of the replaced component, on the relacement application date minus 1 day (the application date can be set in the future, thus allowing a provisional replacement).
The new links with the replacement component are created with a validity start date that is equal to the application date, and to the same sequence number as the replaced link. If the replacement creates an already existing reference to the same sequence, the corresponding link is created upon sequence n+1 (n+2 if the component already exists as n+1, etc.).
Moreover the quantity of the replaced component can be modified for the replacing component (in the absence of strict equivalence between both references), via the manual entry of a multiplying factor of the link quantities.
The calculation of the lower-level code is carried our for the replaced and replacement components, and for the update of the "Where-used" flag.
Refer to documentation Implementation
The component replacement screen is subdivided into two parts:
This is used to supply selection criteria:
Presentation
The other screen displays the list of the selected components, using the component to be replaced, with the modifications already carried out (new component, validity start date and link quantity).
If both production and sales codes have been selected, the links appear in two different grids corresponding to each code type. These grids are present in the "Component product (Production)" and "Component product (Sales)" tabs.
The validation screen includes a first column "Yes/No" to validate (Yes) or exclude (No) the replacement for the link. By default the validation column displays the value "Yes", except for links with anomalies:
The Validation button is used to start the replacement processing for all the links ticked in the grid, and the manual modifications made are taken into account.

Fields
The following fields are present on this tab :
Grid Production links
|
This field is used to validate (value "YES") or exclude from the process (value "NO") the selected lines. |
|
Multiple bills of materials (BOMs) can be defined for a single product. Each BOM code can be assigned specific management features. For manufactured or subcontracted products this includes restriction of the BOM to a specific site and to specific areas of functionality (for costing or for capacity planning). |
|
This product code describes what is referred to as a "Bill of Materials" or a "BOM". A BOM contains structured information for making and costing a product. It defines the components that make up a product, and given this, the cost of the product. The BOM code matches the product code. |
|
This field identifies the sequence number of this component in the BOM (bill of materials). |
|
This field displays the unit of measure (volume or mass). |
|
This is the conversion coefficient between the operation unit of the component and the storage unit. |
|
|
|
|
|
Use this field to define the rounding rule to be applied to adjust the calculated quantity of this component to the number of decimal places defined for the stock unit of the parent product. You can set this field to one of the following values:
|
|
The base quantity entry depends on the management unit chosen:
|
|
The management unit is used to define the quantity of the BOM links on another basis than the product unit. |
|
|
|
|
|
For components that are managed b y lot, this is the first lot for which this link is valid. |
|
For components that are managed b y lot, this is the last lot for which this link is valid. |
|
|
The operation lead-time is used during launch and in the MRP calculations. It is used to calculate the date of the component (material) requirement with respect to the production start date of the parent product. It is expressed in calendar days. You can enter a negative value. Example: A work order has a start date of the 26/06:
|
|
Leave as 'Yes' if the value of this component must be taken into account when calculating the standard cost of the parent product; if the value of this component must not be included in the standard cost, set to 'No'. |
|
Use this field to specify if this component must be printed on work order material issue slips. |
|
Use this field to inform warehouse staff of any actions that apply when this component is picked for issue. You can select one of the following actions:
|
|
Used this field to define the tolerance value to apply when weighing a material. The value you select affects the weighing tolerance fields. You can select one of the following levels:
Note: This field is only available when the MWM-Weighing station activity code is active. |
|
This field displays the percentage used to calculate the weight variance. You can only modify this field if the Setup level is set to BOM. If the Setup level is SHI record or Product-site, this value is based on the Product-sites setup. (GESITF) Note: This field is only available when the MWM - Weighing station activity code is active. |

Fields
The following fields are present on this tab :
Grid Production links
|
This field is used to validate (value "YES") or exclude from the process (value "NO") the selected lines. |
|
Several BOMs can be defined for the same product reference. The various BOM codes can be used to manage different product structures according to their use context such as:
This field can be left empty (value = 0) to enable manual entry of the components. In this case, only the component is loaded. |
|
This field indicates the product reference code. It is generated by a sequence number counter (set up in function Sequence number counters) in the case when the product category has a sequence number counter code. The reference cannot be modified. It is automatically assigned and displayed when the product creation is complete. |
|
This field identifies the sequence number of this component in this BOM (bill of materials). It identifies a component where multiple components with the same product code are defined as variants or options. The BOMSTE - Component sequence increment parameter (TC chapter, BOM group) defines the first sequence number and the increment applied to subsequent component sequence numbers. |
|
Product management unit. This is the unit expressing the quantities in the product management functions. If the asset is created from the capitalization of the expenses, this field is loaded by default with the unit of the main expense. |
|
This field indicates the UOM-S conversion coefficient used to calculate the quantity in US, from a quantity entered in UOM: Qty in US = Qty in UOM * coeff. |
|
It is the allocated quantity expressed in UOM unit. |
|
The link quantity specifies the number of components required for the basic quantity of the parent product. |
|
Use this field to define what type of component this is. You can set it to one of the following values:
|
|
The code of the link quantity can be:
|
|
The quantity of BOM links is entered with a maximum accuracy, which is not always useful for the stock management. |
|
The base quantity entry depends on the management unit chosen:
|
|
The management unit is used to define the quantity of the BOM links on another basis than the product unit. |
|
The loss percentage is used to increase the link quantity in order to take into account the loss due to the production process.
|
|
The validity start date is the date from which the link is valid. |
|
The validity end date is the date beyond which the link is no longer valid. |
|
Enter the short description. By default the short title, the long title or the column header of a data are recorded (on creation/update) in the connection language of the user.
A user who logs on with this language will view the short description, long description or column header in their connection language if a translation exists. Otherwise, these descriptions will be available in the folder language.
