# CostGuard Version 21.12 Details

#### [CostGuard Version 21.12 Core Bulletin](https://cdn.us.document360.io/3f7f8ade-bcb1-4ec8-af25-0c0ad8601afb/Images/Documentation/CostGuard-21.12-Core-Release-Bulletin(1).pdf?sv=2026-02-06&spr=https&st=2026-11-14T10%3A51%3A22Z&se=2026-11-14T11%3A51%3A22Z&sr=c&sp=r&sig=EdAFtKpGFvlP8vyGgSmIkrzmnmpq1Kvb9ySkvELcuOU%3D)

#### Change Orders

| **Functional Area** | **AR/FR** | **Description** |
| --- | --- | --- |
| Customer Care | AR 8759 | **Generating and previewing a *prebill* invoice** Customer Care lets you view and compare invoices on a customer’s account, including *Prebill* invoices. Prior to this release, Prebill invoices could only be generated by the IDI billing team or by submitting a request from E-Support This new functionality lets you generate prebill invoices directly from Customer Care. Also, the term *Prebill* in Customer Care has been updated to *Preview*. |
| Security | FR 3433 | **Web Login Via MicrosoftEdge** Before this change, the IDI Web Login form was presented using an Internet Explorer web browser. With this change, the Web Login form can now be presented using a Microsoft Edge-based web browser. To take advantage of this new behavior, Microsoft WebView2 Runtime — a free, separately installed component — must be installed on each machine that will be running IDI Desktop Client. The Web Login form will safely fall back to using Internet Explorer if the WebView2 Runtime is not installed. |
| AppleCare Equipment Protection Plans | AR 8960 | **Do not send MRC parameter with pay-up-front transaction** The AppleCare Processor was updated to allow nulls for MRC value. If the value is not specified, do not send a value, otherwise send *Y* (Yes) or *N* (No). |

#### Resolved Known Issues

| Functional Area | PR | Description |
| --- | --- | --- |
| Customer Care/CostGuard Client | 83877 | **Issues with Disallow Checks/ACH setting** CostGuard version 20.6 provided a manual account-level *Disallow Checks/ACH* setting in CostGuard Client and Customer Care to prevent the account from making payments via check and creating/using ACH E-Pay accounts. CostGuard version 21.4 (AR 8828) built on this by providing the ability to automatically set *Disallow Checks/ACH* when creating a new account based on the account type*.* This automated functionality is controlled by the *Disable ACH/Checks* setting available via **MANAGE** > **Settings** in Customer Care. Two issues were found related to these settings: When *Disallow Checks/ACH* is set (either manually or automatically) an alert should be added to the account to let users know why they cannot perform check/ACH transactions. This occurs correctly when *Disallow Checks/ACH* is set manually; however, alerts were not being applied when it was set automatically by *Disable ACH/Checks* based on account type. Also, when accounts were created through the Customer Care web module, and *Disallow Checks/ACH* was set on the account, the setting was not being saved. This occurred whether it was set manually or automatically. As a result the alert was not added to the account, and account was allowed to make ACH payments and create/use ACH E-Pay accounts. This solution resolves both issues: The alert is now correctly displayed on accounts where *Disallow Checks/ACH* is automatically set using *Disable ACH/Checks*. When you add an account via Customer Care and *Disallow Checks/ACH* is set, the account behaves accordingly. > [!NOTE] > **Note:** > > With this solution, you can also automatically turn off *Disallow ACH/Checks* and the corresponding alert using the Modify Customer trigger. This can be used if the system is configured to not allow ACH/checks when a prepaid account is created, and the account type is subsequently changed to a type where this should not apply. |
| Customer Care | 83824 | **Correlation ID error on billing order screen in Customer Care** Several PRs have been deployed to improve performance when loading billing orders on the Order History page in Customer Care. PR 83538 addressed the view for customers on SQL 2017 in CostGuard version 20.9, while PRs 83589 in CostGuard version 21.01 and 83667 in CostGuard version 21.6 addressed the view for customers on SQL 2014. PR 83824 provides additional optimizations to reduce timeouts for customers on SQL Server Management Studio (SSMS) 2014. |
| Orders | 83820 | **Overlapping service number error on newservice order** When using workflow splitters to add a parent/child service, if the child service was added first, the add child order resulted in adding a parent service. Subsequently when the parent service order ran, a second parent was added. To prevent this, the parent service is now marked as *processed* in the first order so it is skipped in the second one. |
| Orders | 83884 | **Error on disconnect order from treatment workbook** Errors were reported (cart remained in a submitted status) when attempting disconnects through the Treatment workbook. This occurred when the system was handling a higher than average amount of processing. To avoid this Order Placement logic was updated to process these requests in a more efficient manner. |
| Orders | 83892 | **Unable to reconnect service – object reference error** Object reference errors were thrown on services where the MIN was in *Reserved* or *Aging* state. The logic was not checking to see if the *objInvServiceNumber* value was null before checking if the item was already in use. This was resolved by applying similar logic for MINs in *Reserved* or *Aging* state that currently applies for MINs in *Not Available* state. |
| Customer Management | 83803 | **Contact Modified trigger doesn’t fire during edit contact for primary/billing** When modifying a billing contact in CostGuard Client by double-clicking on the Edit Contact menu, the contact modified trigger was not firing. This issue has been corrected. Testing Notes: In workflow create a contact modified trigger to pick up your edit In CostGuard Client, go to the *Contact* tab and double click on the billing contact This opens a generic edit contact screen. Make a change and save. Confirm the trigger fires. |
| RateBill Taxes | 83874 | **County taxes to skip updated** An issue was preventing a county level tax marked as *primary* from being skipped in certain conditions when a city level tax was configured to skip the county tax. The tax engine has been fixed to skip the county level taxes in this condition. |
| CPNI | 83821 | **Customer Care CPNI notification failed to find/use custom template** In some cases, CPNI PIN notifications were sent using the wrong notification template. This could only occur when a CPNI PIN notification was sent as a result of user activity from the Customer Care web application and a custom template was configured for the CPNI PIN notification. Note that CPNI PIN notifications sent as a result of user activity from CostGuard client are correctly sent using the custom template if a custom template exists. This issue occurred when the custom CPNI PIN notification template was saved in the database with mixed case in the key name (CPNI.Pin versus CPNI.PIN) Customer Care has been updated to correctly use a custom template for CPNI PIN notifications. |
| Compliance Revenue Recognition Standards | 83906 | **FASB ASC 606 – Incorrect calculation of Contract Asset Value** The formula for Contract Asset Value coded in AR8760 (released in CostGuard 21.05) was not correct and was miscalculating these values. The formula was updated as follows: Contract Asset Value = (C*D*M) / (C*M +S) where M = MRC of plan S = Total Stand Alone Price of Qualifying Retail Items D = Total of Qualifying Discounts C = Contract Duration |
