📄 Variant

Variant

The Variant model is one of the core components of Bimbal. It represents a set of changes applied to a 📄 BIM. 
Each Variant contains the additions, removals, or modifications you would apply to his BIM.

Together, Variants form the full evolution of the BIM over time.

💡

See📄 Glossaryfor the exact definition

A Variant records incremental changes to the BIM: added items (+), removed items (–), or unchanged values (0).
Bimbal compiles the Variant Lines and merges them into the BIM.

⚠️

Important
Only Lines from confirmed Variants are merge in the BIM Lines, ensuring full control and traceability over the project lifecycle.

How a Variant Works

  • A Variant can be created at any time to record a new set of changes
  • One Variant = one group of modifications to one BIM
  • Variants contain Variant Lines, which correspond to the BIM Lines they affect
  • Only confirmed Variants contribute to the BIM fusion
  • Variants allow you to structure every change from the initial design to the As-Built state of the BIM
  • Variants can be viewed, filtered, exported, or used for technical, financial, or contractual review
  • With Bimbal, an offer is always created from a Variant

Key Variant Fields

Here are the main fields and features of the Variant model:

Name
The Variant name (e.g., V03 – Customer Electrical Request) is an identifier set freely by the user (id, is the Variant unique identifier)

Variant Lines
All changes are encoded through Variant Lines (additions, removals, unchanged quantities).
These lines are later merged into their corresponding BIM Lines.

State
  • New (status when a variant is created. This status allows the variant to be edited)
  • Locked (status automatically activated if SO generated. Does not allow editing. Does not total quantities in BIM)
  • Sent (status automatically activated if SO sent to customer via chatter. Does not allow editing. Does not total quantities in BIM)
  • Cancelled (status automatically set if SO cancelled. No longer allows editing. Cancels quantities in BIM)

NB: it is possible to modify the status of a variant directly in the variant edition popup, without going through the SO. This can be used, for example, to take into account variations in quantities without customer implications

.

⚠️

Important: 
A state change made directly on a variant does not lead to a change on the SO side.


Sale Order
A Variant can optionally be linked to a Sale Order.
If the Sale Order is confirmed, the Variant is automatically confirmed.

⚠️
Important
Even if confirmed, a Variant may not have a Sale Order. This is used for internal variations (Changes with no impact on the client side)
Financial Fields
Such as:
  • Total Cost
  • Subtotal
  • Margin
These values reflect the financial impact of the Variant on the BIM.

Sales Fields
Sales parameters inherited from the BIM. These act as default values when creating a Variant line:
  • Fiscal Position
  • Invoice Address
  • Delivery Address
  • Pricelist
Role of Variants in the Project Lifecycle
Variants allow you to:
  • Track every modification, internal or requested by the client
  • Keep a full audit trail of all changes
  • Simulate scenarios or alternatives
  • Confirm only what is contractually agreed
  • Consolidate confirmed changes into the BIM
  • Maintain a precise As-Built state of the BIM

Variants ensure transparency, control, and traceability throughout the entire project.


Default values ​​in the lines of a new created Variant :

(The logic below applies when creating a new Variant but not when duplicating a Variant)
When you create a new Variant, Bimbal will apply the following default values for each line: 

Priority

Situation

Field: Quantity

Field: Unit Cost

Field: Compute Mode

1

If the line have no parent product line:

Zero value

Cost value of the product (except if computed by child lines values)

Value "C"

2

If the parent line has been used (based on non-zero Total Quantity) in at least one confirmed Variant:

Value from this line in the oldest confirmed Variant (based on lock_date) where the parent line has been used

Same

Same, except Mode "F"
(Mode "F" will be switched to Mode "I")

3

If the parent line has not been used in any confirmed Variant:

Value ​​from the corresponding BoM (if the line belongs to a BoM)

Cost value of the product

Value "C"

4

If the line does not belong to any BoM:

Zero value

Cost value of the product

Value "C"
