This document outlines the functional specifications for a project to implement cost adjustments in Openbravo. It includes an overview of cost adjustments and their purpose. The design considerations cover assumptions, dependencies, and constraints. Business processes, user stories, and functional requirements are defined for cost adjustment functionality including standard cost corrections, landed costs, and balance amount updates. Technical requirements and open discussion items are also noted.

These modifications can be needed by different causes. Backdated transactions or landed cost are the most common. Purpose Current Cost Engine is based on Perpetual Costing. This means that any calculated cost shouldn't be modified. Because of this restriction there are some cases that currently cannot be resolved. To solve this Cost Adjustments are needed. With this project it would be able to fix unexpected cost results when transactions are not registered in the system in the same order that happened or to implement landed costs. Scope The scope of this project is to create a new functionality to manage cost adjustments. This project also enables the possibility to create modules with processes to adjust costs. References This project is an extension of the Costing Engine, deep knowledge of this functionality is required. Design Considerations Assumptions The Cost Adjustment process should be possible to be extended by modules. Dependencies Existing core processes retrieving transaction costs should be reviewed to ensure that adjustments are included when needed. http://wiki.openbravo.com/wiki/Projects:Cost_Adjustments/FunctionalSpecs 1/5
- 2. 6/25/2014 Projects:Cost Adjustments/FunctionalSpecs - OpenbravoWiki Existing core algorithms (average and standard) should be updated to implement cost adjustments. Constraints Costing Algorithms need implement new methods for cost adjustments. Algorithms not upgraded should not break the application. Glossary Functional Requirements Business process definition 1. New document Cost Adjustment 1. Header with the adjustment definition, includes cause, type,... 2. Lines with all the transactions affected by the adjustment. 2. Algorithms are in charge of populating the involved lines of the Cost Adjustment when a transaction is adjusted. 3. The process that searches the transactions involved and calculates the adjustment amounts: 1. Needs to take into account the possibility of a Costing Rule change. 2. Changes in amount of outgoing transactions is the only case where no other related transactions are affected. There is an exception on closing inventories of Costing Rule initializations. 4. The cost adjustments are generated by 3 different processes: 1. Standard Cost Corrections: 1. Fixes transaction costs known to be not accurate. 2. It fixes the transaction and all the related ones. 3. The process is done for a reference date. 1. The process searches transactions that require adjustments up to the reference date. 2. Involved transactions can be on a later date. 3. The process ensures a synchrony between ledger balance and inventory balance only on the reference date. 4. Transactions that require adjustments: 1. The order of the transaction calculation is not correct (backdated transactions) 2. Differences in order/invoice prices. 3. Order price modification with receipt cost calculated. Under discussion if this scenario is possible. 5. Products without stock but with a balance in the ledger or inventory different to zero. 2. Landed Cost: Ability to assign additional costs to single transactions. Usually freight costs or custom taxes to receipts. 3. Ability to update the balance of a product on a date to an specific amount. 1. The process generates closing/starting inventories whose calculated cost is the old balance (closing inventory) and the new balance (starting) 2. If this process is done for a date in the past a cost adjustment will be needed. 5. Cost adjustments are cumulative. A single transaction can have several adjustments. 6. The process to search for involved transactions needs to take into account consumed goods transactions of manufacturing. Both BOM and Work Efforts. 1. In this case the related produced goods costs needs to be adjusted as well. 7. The accounting of the adjustments is not driven by the Cost Adjustment document. 1. New document/process to post adjustments to the ledger. 2. A accounting date is set as reference. 3. All adjustments pending to be posted prior to the reference date are posted on a single journal entry on the given accounting date. 4. It is not possible to close an accounting period with adjustments pending to be posted. User stories Case 1 Closing a period with backdated transactions. 1. Ann want to close an accounting period. 2. She knows that in that period there were some shipments that were not entered in the same date. 3. She creates a new Cost Adjustment to check for backdated transactions up to the last date of the period she's closing. 4. She process the cost adjustment. 5. On the lines she can review all the transactions that have been updated. Case 2 A shipment is entered on a later date http://wiki.openbravo.com/wiki/Projects:Cost_Adjustments/FunctionalSpecs 2/5

He creates a new Cost Adjustment for the receipt setting the correct date. 4. He processes the cost adjustment. 5. On the lines he can review all the transactions that have been updated.
