[edit] Info
- parent mantis - http://ct.jaguarfreight.com/mantis/view.php?id=837
Scope:
This covers "Currencies and Exchange Rates" admin part of Accounting component.
[edit] Business Needs and Requirements
[edit] Formulas
Exchange rates are used in many places in the system to convert from one currency to another.
We use several different formulas now in different places.
[edit] v1
Rate used is based on the date associated with invoice:
- For Sales Invoices it is Sales Invoices#Issuing Date
- For Purchase Invoices it is Purchase_Invoices#Date
[edit] v2
- base exg rates on "CT created on" date until "actual arrival" date is set (for both Purchase and Sales invoices)
- after actual arrival is set base exg rates on that date
- in case of group use dates from CT with lowest CT number
Note ----- Currently, On PI level in case of Master if say amount posted is in euro then code will first identify euro amount for each CT and then convert separately and then combine them to identify PI amount for the group.

[edit] Summary
Exchange Rate is a number assigned to an ordered pair of currencies (Currency1, Currency2). Example: (USD, GBP, 0.63).
In finance, the exchange rates between two currencies specifies how much one currency is worth in terms of the other (wiki).
Each Jaguar Office has its own Exchange Rates.
[edit] User Interface and Functionality
CT2 User can view and edit the Exchange Rates on the separate tabs of Currencies And Exchange Rates Home:
- View - on View Exchange Rates tab

[edit] View
- For each currency X in the system displays all pairs (currency Y, exchange rate from X to Y ) for current office. See Figure 1
- columns:
- Currency From (X)
- Currency To (Y)
- Exchange Rate
[edit] Edit
- see Figure 2
- steps:
- select "Currency From:" from the dropdown list
- edit whole and decimal parts for required Currency To
- click "Save All Changes"
- (re)defining exchange rate from X to Y would automatically (re)define exchange rate from Y to X
- (In other words, if X is set then Y will be automatically re-calculated as Y=1/X. And vice versa).

Client Exchange Rate is a number assigned to an ordered triple of (Client Company, Currency1, Currency2). Example: (Coty, USD, GBP, 0.63).
Each Jaguar Office has its own Client Exchange Rates.
[edit] User Interface and Functionality
CT2 User can manage the Client Exchange Rates on the special tab of Currencies And Exchange Rates Home - Client Company Exchange Rates. See Figure 1.

- Form in Pop-up will appear.
NOTE: Unlike the general Exchange Rates, (re)defining exchange rate from X to Y wouldn't automatically (re)define exchange rate from Y to X. It means that setting (Client Company, Currency1, Currency2) will not automatically set (Client Company, Currency2, Currency1).
[edit] Remove
- Select one or more items on the list and click "Remove"
- System presents message:

[edit] SOW 1
0002812: bugs/changes: 1) bug: Two GBP currencies listed in the system 2) add archive feature for currencies
[edit] Core Requirements
Archiving feature has the following on Currencies Tab:
- add Archive/Restore and Replace buttons and "Hide archived" checkbox with appropriate functionality for new 2012 standard
- "Archive" button: get user confirm, mark as archived with image
- "Restore" button: get user confirm, remove "archived" mark
- "Replace" button: get user confirm, "merge" two items into one
- "Hide archived" checkbox:
- if checked then don't display archived Currencies in table,
- if unchecked then display all
- add column with a garbage can to mark archived items in table of Currencies
[edit] Related Functionality
- Provide recording (and displaying) of all archive-related actions with Currencies in System Log
- For every place in the system where currency is appearing:
- if currency is tagged as archived then it should not appear on the list
[edit] SOW 2
0003577: add Currency Code validation to prevent duplication of Currencies
[edit] Core Requirements
We need some sort of validation of what user enters to make sure it's not a duplicate.
- Example: gbp (in lower case) & GBP (in upper case) are the same so the system should not allow it to be saved because its a duplicate.
[edit] Solution
- Every Currency Abbreviation should be unique in CT2.
- System should provide entering of Currency Abbreviation in CAPITAL letters only.
- Validation should work upon creating and editing of Currency (in Add/Edit Currency window).
- Comparison should include archived Currencies also.
[edit] Related Functionality
- Archive feature for Currencies will be done under mantis 2812
[edit] SOW 3
0004723: Redesign of Exchange Rate UI and functionality
[edit] Core Requirements
- Stop mirroring rates between currencies
- 2 converted Currencies DOES NOT REFLECT / MIRROR / RELATE / IMPACT / ANYTHING
- Duplicate rate interface - for SALES and for PURCHASES
- We need to duplicate the exchange rate interface, and apply 1 side for SALES and the other side for PURCHASES
- Per Office? NOT CONFIRMED
[edit] Solution
- Stop mirroring
- Any two Currencies should not use reverse calculation of Exchange rate between them
- Each direction of Exchange Rate should be updated separately from its pair
- Example: "USD to GBP and "GBP to USD" are 2 separate entries in the System
- Sales/Purchase Rate type
- From release 2.38.0 we started to use two types of Exchange rate instead of the one used previously:
- "Sales/Internal" Rate Type should be used for calculation in Sales and Internal Invoices and related reports
- "Purchase" Rate Type should be used for calculation in Purchase Invoices and related reports
- Saving the updates entered in one Type section should be proceeded before switching to other Type section
- Exchange Rate history is kept in DB for each Type of Rate
- Global level of Exchange rates
- ONLY 1 SET OF EXCHANGE RATES FOR THE ENTIRE SYSTEM - NO MORE "PER OFFICE" EXCHANGE RATES.
- Date when we starting to use Global Rates: 24-Jan-2015.
[edit] Figure 1: Redesigned Exchange Rates UI.
[edit] Related Functionality
- 0004764: Correct some Exchange Rates and re-calculate all related conversions.
- 0004780: Provide 6 decimals in Exchange Rates.
