Since CE2008, Bill of Materials (BOM) can be handled in Manage Customer Return App.  Right now, it can support two BOM variants:

ERLA: Pricing and inventory management for BOM main item, components are processed as ‘explanations’

LUMF: Pricing and inventory management for the BOM components, main item is processed as ‘explanation’.

In general, BOM can be supported in Manage Customer Returns from creation to determining refund procedures.

Accelerated return now can be created with BOM material from preceding sales order and invoice. The component quantity is auto calculated when you input the BOM main item’s quantity or unit of measure.

The return reason, logistic follow up activity can only be set at main item and it auto transfer the value to components.

For refund settings, it can be enabled at BOM main item or components depending on BOM Variant.

For ERLA variant, the main item can be refunded with credit memo.

For LUMF variant, the components can be refunded with credit memo or replacement material.

In determine refund phase, the BOM complete the refund when all refundable (main item or components) finish the corresponding refund.
