I created an Asset and configured all required fields, but the depreciation schedule/lines are not generated

I created an Asset and configured all required fields, but the depreciation schedule/lines are not generated. Tried all options I could find:

  • Action menu items related to “Create Lines / Compute Lines / Recompute / Draft → Running”, etc.

  • Switching tabs (Lines / Other Info) and saving again.

  1. Result: no depreciation lines are created (Lines tab stays empty). No error message is shown in the UI. What could prevent Tryton from generating Asset depreciation lines?

    • Missing configuration (accounts, journal, company settings)?

    • Access rights/workflow state?

    • Known issue in SAO / assets module?

    • How can I force recompute of lines (schedule only), without creating accounting moves?

    Thank you.
