Tutorial: Floor Life and Expiration Date Propagation#

Estimated time to read: 2 minutes

Objective#

Learn how to configure and validate the propagation of floor life and expiration date during material operations, ensuring that the most critical material conditions are preserved throughout assembly.

Step 0: Validate Preconditions#

Before executing propagation, ensure:

  • Source materials have:

    • Floor Life defined
    • Expiration Date defined (if applicable)

  • The relevant Product Revision has:

    • SMTPropagateFloorLife = true (if floor life propagation is required)
    • SMTPropagateExpirationDate = true (if expiration propagation is required)

  • A valid BOM exists (for assembly scenarios)

Step 1: Configure Product for Propagation#

  • Navigate to the Product and enable:
    • SMTPropagateFloorLife = true
    • SMTPropagateExpirationDate = true

This ensures that materials of this product, when consumed, will propagate these properties during assembly operations.

Step 2: Prepare Materials#

2.1 Define Source Material Conditions#

  • Create or identify consumable materials
  • The materials should have set:
    • A floor life remaining time
    • An expiration date

Ensure at least one material is more critical (e.g., earlier expiration, lower remaining floor life)

2.2 Prepare Target Material#

  • Create or identify the target material (e.g., Board)
  • Verify its current:
    • Floor life
    • Expiration date

Step 3: Execute Assembly Operation#

  • Perform one of the supported operations:

    • Automatic Assemble Material (recommended for this scenario)
      (or any supported operation like Assemble, Combine, Compose)

  • Ensure materials are correctly assembled and processed

Step 4: Validate Propagation#

  • After execution, open the target material

  • Verify:

    • The expiration date is updated to the earliest from source materials
    • The floor life remaining reflects the lowest available value

Expected Result#

  • Target material inherits the most critical values:

    • Lowest floor life remaining
    • Earliest expiration date

  • If the target already had more critical values:

    • No changes are applied

Frequent Configuration Questions#

Why is no propagation occurring?#

Check that the product attributes are correctly configured:

  • SMTPropagateFloorLife
  • SMTPropagateExpirationDate

Why is propagation only occurring partially?#

Ensure that both attributes are enabled. Floor life and expiration date propagation are independent and must be configured separately.

Why is the target material not being updated?#

The target material may already contain the most critical value. This is the expected behavior.
