# Known Issues & Gotchas

Whilst we have tried our very best to create the most seamless possible experience for Maica users, there are some known issues and 'gotchas' that we have found along the way.

We have listed these below and, where possible, the resolution and/or work-around.

## Duplicate Rule Clash

As part of a Maica package **install or upgrade**, you may receive the following error:

```
SortOrder must be in sequential order from 1.
Account.ABN_Matching: SortOrder must be in sequential order from 1.
```

This is due to a duplicate rule on the standard `Account` object that is included in Maica to assist in the management of your Providers and Organisations.  The details are below:

* **Matching Rule Name**: `Maica ABN Match`
* **Matching Rule Criteria**: The Matching Rule Criteria looks for an **EXACT** match of the data entered into the Maica `Australian Business Number (ABN)` field on the `Account` object
* **Duplicate Rule Name**: `Maica ABN Duplicate Rule`
* **Duplicate Rule Conditions**: `Account`: `Australian Business Number (ABN)` NOT EQUAL TO `null`

In order to solve this, you need to have **a second** Duplicate Rule on the `Account` object.  If you already have one (which many users will) then great, otherwise you can use the standard Salesforce rule.  This is appropriately called the `Standard Account Duplicate Rule`. 

This Duplicate Rule can be found by navigating to `Setup` and typing duplicate as per the image below:

Once you have found the Duplicate Rule, you need to do the following to solve the `SortOrder` issue and install or upgrade the Maica package:

1. Click the **Reorder** link (see above)
2. Click the **Order** arrow (in green) and ensure that the `Maica ABN Duplicate Rule` is not the first Rule in the list, i.e. **it is not Order = 1**

Once you have completed the steps above, you should now be able to successfully install or upgrade Maica in your Salesforce instance.

{% hint style="info" %}
If you already have your own Duplicate Rule(s) on `Account`, you can use this **instead** of the `Standard Account Duplicate Rule` described above.

This one falls more into the gotcha category than known issue.
