Problem

The second test migration into NovaERP stopped at the bill of materials (BOM) import. 1'214 of 3'870 BOMs failed. All failed BOMs are variant BOMs that were copied by hand in BW-Classic between 2009 and 2015; many point to parts that no longer exist.

Workaround

Reto Ammann skipped the failed BOMs to test the rest of the import. Finance and purchasing data imported cleanly.

Decision: Clean up the legacy variant BOMs in BW-Classic before the migration instead of migrating them as they are.
Why: about a third of the variant BOMs point to parts that no longer exist; migrating them would copy the mess into NovaERP.

  • Action: @Lukas Brunner mark which variant BOMs production still uses (due 2026-08-28) (done)
  • Action: @Reto Ammann delete or archive the unused variant BOMs (due 2026-11-20)
  • Action: @Reto Ammann run the third test migration (due 2026-11-27)
