"It is not possible to unreserve more products of <product name> than you have in stock"
Sometimes, the reserved_quantity on the stock.quant record for a product becomes out-of-sync with the sum of the reserved quantity in stock.move.lines for that product.
For example, consider:
- Product A (quant): on-hand = 50, reserved = 10
- Picking A (move): reserved = 10
- Picking B (move): reserved = 5
As we can see, Product A thinks that 10 units are reserved, when in reality, 15 units are actually reserved in pickings. If we try to validate/cancel/unreserve Move A and Move B, we'll get an error like above, because un-reserving 15 units would leave us with -5 reserved! Note that this prevents cancel, unreserve, AND validate.
This seems to be an edge-case bug, that may have been fixed in a recent (circa 2021-05-01) patch to Odoo (for v14, at least).
Note: This script was inspired by amoyaux's gist, which will show any discrepancies, but won't update any DB tables. Link here: https://gist.github.com/amoyaux/279aee13eaddacbddb435dafbc0a6295
Fixing this issue is easy: We just need to update the reserved_quantity field on stock.quant to match all open stock.move.line records.
