The price and value on an issue note are not entered manually — ABRA Flexi always calculates them according to the configured inventory valuation method. Occasionally, the value on an already existing issue note changes on its own. Described below are the situations where this is expected behavior.
When the value on an issue note changes
After a subsequent receipt and settlement of issue requests. This occurs after a subsequent receipt and settlement of issue requests (even if the requests are not settled manually and a new issue note with a request is simply created after the receipt — the request from the previous issue note is settled and a new one is created). This is described in detail in the article on updating issue requests.
After a retroactive price change on a receipt note. If you change the price on a receipt note that already has associated issues, the new price is propagated through FIFO links to all related issue notes. This is ensured by the inventory recalculation, which in this case is triggered automatically.
The price on an issue note cannot be overwritten
The Price per unit field on an issue note is for informational purposes only and cannot be edited in the application. This is intentional: the issue price represents the actual cost of the issued goods and must match the price at which the goods were acquired. If a user could overwrite it, the inventory value would no longer match the value of the inventory movements.
🚨 Never bypass the price on an issue note via the REST API
It is technically possible to enable manual price entry on an issue note via the API and write the value. Do not do this, not even for integrations and implementations. The result is a mismatch between the inventory quantity and its value in currency, which usually only becomes apparent after some time and can be difficult to trace and correct.
