Summary

0045844: Error on Fix Backadated Transaction process. A trx is wrongly considered as backdated

Description

The fix backdated transaction is not checking the transaction dates by product. This can lead to false positives and adjusting transactions that are not backdated.

Having the following transactions processed in the given order:
Product A mvt date 01-01-2021
Product A mvt date 10-01-2021
Product A mvt date 01-02-2021
Product B mvt date 20-01-2021

The fix backdated transaction process tries to adjust as backdated transaction the last trasnaction from product B because the previous transaction from Product A has a newer movement date. This is wrong, the transaction from Product B has to be compared with other transactions of the same product.

If the fix backdated transactions are already enabled in the costing rule that transaction won't be automatically adjusted as backdated.

If the false positive is the 1st transaction of the product the process fails with an error:

Steps To Reproduce

On F&B España.
Check that Costing Rule does not have the fix backdated transactions enabled.
Check the newest transaction movement date on some products.
Create a new product and set a purchase price.
Create a receipt for the new product with a movement date in the past. Ensure that it is a date older than the checked for other products.
Ensure that the cost of the receipt is calculated.
Go to Costing Rule and execute the Fix Backdated transactions process. Set a starting date before the date used in the receipt.

Proposed Solution

The transaction movement dates shall be compared on same product transactions. Change the getTransactions method to sort the transactions also by product and modify the transaction loop to manage when the product changes.
