In Microsoft Dynamics AX (X++), there are many scenarios where you need to duplicate data from one table to another—especially during custom import, duplication, or versioning processes. Traditionally, this is done by manually assigning each field: targetTable.Field1 = sourceTable.Field1; targetTable.Field2 = sourceTable.Field2; ... But what if the tables have many fields ? Or maybe you’re dealing with multiple similar table pairs? That’s where the powerful DictTable class comes in. Let’s walk through how to use it to copy matching fields dynamically between two tables. 💡 Use Case: Copy Customer Templates Let’s assume you have these tables: CustTemplateHeader – stores predefined customer templates. CustTemplateHeaderHistory – a historical copy of templates for versioning. You want to copy records from CustTemplateHeader to CustTemplateHeaderHistory , but only for fields that exist in both tables. ✅ The Solution Using DictTable SalesHeaderTemplate ...
X++ is a high-level programming language used primarily in Microsoft Dynamics 365 Finance and Operations. Understanding how variables work in X++ is fundamental for managing data and performing various operations within the ERP system. What is a Variable? A variable in X++ is an identifier that points to a memory location where data of a specific type is stored. The characteristics of a variable, such as size, precision, default value, and range, depend on its data type. Variables are crucial for storing and manipulating data during the execution of a program. Variable Scope The scope of a variable defines where it can be accessed within the code: Instance Variables : Declared in class declarations and accessible from any method within the class or its extensions. Local Variables : Declared within a method and can only be accessed within that method. Declaring Variables When you declare a variable, memory is allocated, and the variable is initialized to its default value. Variable...
