Update and Compare Construction Orders

In complex manufacturing environments, you often need to compare and synchronize similar technical structures without rebuilding them from scratch. The Construction BOM Compare & Update feature lets you compare a source structure with a target structure and selectively apply differences — with full user control.

With this feature, you can:

• Detect insertions, deletions, modifications, and movements based on configured fields and hierarchy context.
• Review all changes in a structured dialog with clear visual indicators.
• Apply selected changes to the target while retaining full control over each step.

The comparison logic supports:

• BOM structure (Construction Lines and sub-lines).
• Manufacturing Data (dimensions, attributes, quality, tools, personnel).
• Field-level differences based on BOM compare field configuration.
• Recursive comparison for nested Construction Lines (via the Belongs to Entry No. relationship).
• Movement consolidation: uniquely detectable parent changes are shown as "Move" (instead of "Insert" and "Delete").
• User-confirmed updates for full control.

Comparison can be initiated from several sources and applied to the selected target:

• Master data (Production BOM and Routing / Master BOM)
• Construction Order
• Construction Order Archive
• Document BOM
• Document BOM Archive

Note

A common scenario is Construction Order ↔ Construction Order. The same compare mechanism also supports master data → Construction Order, and Document BOM ↔ Construction Order/archive combinations. Changes are always applied to the document you select as the target during compare.

The intended usage model and scope of the Construction BOM Compare & Update feature includes:

• Compare scope: Compares a defined source with a defined target (Construction Order ↔ Construction Order, master data → Construction Order, Document BOM/archives). The engine detects Inserts, Deletes, Modifies, and Moves and lets you apply selected changes to the chosen target.
• Recommended practice for growing BOMs: Model structural decisions in master data and adopt them into Construction Orders at defined milestones/batches. This reduces parallel, conflicting edits across master data and open Construction Orders.
• Move usage: Movement (re‑parenting) is user‑initiated (Auto Move or Move). Only uniquely matchable "Insert"/"Delete" pairs are converted; ambiguous cases remain "Insert"/"Delete" for user decision.
• Out of scope: A generic, rule‑based auto‑adoption engine and fully simultaneous change management across master data and existing Construction Orders are not part of the Compare/Update framework.
