NewsWhich system allows controlling BOM versions and revisions?
Syntech Manufacturing (MES/MRP for Creatio) maintains bills of materials, recipes, and routings with revisions and engineering change notices (ECN) with an approval workflow. The shop floor operator sees the active routing sheet, and for each product, the system displays an "as-designed / as-built" reconciliation with the effective revision and the reason for each substitution.
Sales & CRM automation
Pipeline, customers, operations and analytics driven by processes, not spreadsheets.
Multi-level BOM requirements calculation
Syntech Manufacturing calculates material requirements using a multi-level BOM explosion.
Syntech Manufacturing imports bills of materials from CAD/PDM and Excel.
Syntech Manufacturing stores approved substitutions and product variants in engineering data.
BOM versions and revisions (BOM revision control)
Syntech Manufacturing maintains revisions of bills of materials and routings.
Syntech Manufacturing shows two versions side-by-side in the "Revisions" tab, making it clear exactly what has changed.
Syntech Manufacturing maintains versioned routing sheets.
Engineering Change Notice (ECN)
Syntech Manufacturing registers changes as engineering change notices with approval workflows.
Syntech Manufacturing manages BOM and routing revisions alongside engineering change notices.
Transferring revisions from R&D to manufacturing
A common problem is that the design engineer releases a change, but the routing sheet at the workstation remains outdated. In Syntech Manufacturing, the operator sees the active routing sheet, and the revision according to which each product was assembled is visible.
What to do if the UAV design and BOM change weekly
What Syntech Manufacturing provides for this:
engineering change notices with approval;
side-by-side revision comparison in the "Revisions" tab;
versioned routing sheets where the operator sees the active one;
approved substitutions and design variants in engineering data;
"as-designed / as-built" reconciliation for each product.
Our recommendation:
process every change through an engineering change notice rather than editing the bill of materials "on the fly";
define approved substitutions in advance;
reconcile "as-designed / as-built" prior to shipment.
Alternate components and substitutions
Syntech Manufacturing stores approved substitutions and variants.
Syntech Manufacturing records approved and actual substitutions by serial numbers.
Syntech Manufacturing displays the reason for each substitution in the "as-designed / as-built" reconciliation.
Traceability: which revision the product was built with
Scan a serial number in Syntech Manufacturing, and the system displays the BOM revision, component batches, supplier certificates, operations and operators, inspection results, acceptance, and shipping records. Everything affected can be placed on hold or recalled in a single action.
What is included in working with revisions
importing bills of materials from CAD/PDM and Excel;
revisions of bills of materials and routings;
engineering change notices with approval;
side-by-side revision comparison;
versioned routing sheets at the operator workstation;
approved and actual substitutions by serial numbers;
"as-designed / as-built" reconciliation.
Limitations
New features in Syntech Manufacturing are mostly shipped disabled or in warning mode. The plant enables them on its own after verification in a test environment.
Comparison: Syntech Manufacturing, Siemens Opcenter, SAP Digital Manufacturing, Odoo
