To begin, we would first set up the necessary connections to System A and System B within SnapLogic. We will assume System A has a REST API, and System B has an HTTP endpoint for order creation. Using SnapLogic's REST Snap Pack, we can configure a REST GET snap to retrieve customer details from System A.

Code Snippet:
```
var customerDetails = $.get("https://systema.com/customers", {id: $customerID}); 
```
Next, we can utilize SnapLogic's Mapper Snap to transform the retrieved customer details into the required format for System B. The Mapper Snap allows us to map specific fields and manipulate the data as needed.
Code Snippet:
```
var orderPayload = {
  "customerID": customerDetails.id,
  "name": customerDetails.name,
  "email": customerDetails.email,
  // Other relevant fields for order creation
};
```
Once the data is transformed, we can use SnapLogic's HTTP Snap to make a POST request to System B's order creation endpoint, passing the transformed customer data.
Code Snippet:
```
var response = $.post("https://systemb.com/orders", orderPayload);
```
SnapLogic provides built-in error handling and logging capabilities, allowing us to monitor the integration process and capture any potential errors or exceptions.

            },
            "to": {
                "node": "Mapper",
                "port": "input"
            }
        },
        {
            "from": {
                "node": "Mapper",
                "port": "output"
            },
            "to": {
                "node": "CSVFormatter",
                "port": "input"
            }
        },
        {
            "from": {
                "node": "CSVFormatter",
                "port": "output"
            },
            "to": {
                "node": "csv",
                "port": "input"
            }
        }
    ]
}
```
In this pipeline, the JSON Parser Snap takes the JSON input data, which could be obtained from an API or a file. The JsonPath Snap helps extract specific data from the parsed JSON using JsonPath expressions.

Here is a code snippet showcasing how error views can be used in SnapLogic pipelines:
```python
// Define an error view
var errorView = myPipeline.errorViews.get("Error View");

// Configure snaps to send error documents to the error view
mySnap.errorView = errorView;

// Perform error handling logic
if (errorDocument.someCondition) {
  // Custom error handling logic
  errorDocument.errorType = "CustomError";
  errorDocument.errorMessage = "An error occurred!";
  
  // Log the error using a Logger snap
  loggerSnap.input.view.snapData = errorDocument;
} else {
  // Do other processing on non-error documents
}
```
Another aspect of error handling in SnapLogic is error logging. SnapLogic allows you to log errors during pipeline execution to track and analyze the occurrence and nature of errors. You can use the Logger snap to log error documents to various destinations, such as a file, database, or external logging system.
