In Dynamics 365 Finance & Operations (F&O), a "map" is used for organizing and storing data.
Unique Keys: Just like each word in a dictionary is unique, each 'key' in a map is unique. A key is a label or identifier you use to find a specific piece of data (like a word in a dictionary helps you find its definition).
Data Types: The keys and the data (values) they point to can be of any type. For example, a key could be a number, and the value could be a name or a date.
Efficiency: Maps are designed to let you quickly find data. If you know the key, you can immediately find the value.
Usage: In Dynamics 365 F&O, maps are used to customize how the system works or to connect it with other systems. They help manage and access data in a way that’s easy to understand and use.
In short, maps in Dynamics 365 F&O are like sophisticated dictionaries for storing and finding data, making it easier to manage and use information in the system.
Example:
public static void MapUsage(Args _args)
{
Map empMap = new Map(Types::Integer, Types::String);
// Adding values to the map
empMap.insert(1001, "Atul Yadav");
empMap.insert(1002, "Joris");
// Retrieving a value using a key
info(strFmt("Employee Name: %1", empMap.lookup(1002)));
// Iterating through the map
MapEnumerator mapEnumerator = empMap.getEnumerator();
while (mapEnumerator.moveNext())
{
int empId = mapEnumerator.currentKey();
str empName = mapEnumerator.currentValue();
info(strFmt("Employee ID: %1, Name: %2", empId, empName));
}
}
