About: Expression Functions Mapping

With function expression to field mapping you can run an function from Microsoft Dynamics 365 Business Central to calculate values.

Usage

Use an expression function if you want to manipulate, calculate or enrich the data which needs to be imported or exported. You can use the Expression Wizard to map the arguments of a function with appropriate values. Expression functions can be used both while importing or exporting data from Microsoft Dynamics 365 Business Central.

Concept

An expression function enables Microsoft Dynamics 365 Business Central functions to be called during mapping. Each function can have its own set of arguments. These functions are available to users via expressions. There is virtually no limit on how often this function can be used in an single expression.

Registering

To be able to use functions in the Expression Wizard, the functions have to be registered in the Function Library. This is explained in Expression Function. The function library contains the collection of standard functions and can easily be extended with custom functions.

Standard Expression Functions

Business Integration Solutions comes with standard functions out of the box. Some products may add their own additional set. These are registered during product installation For a list of all the standard functions see Expression Function
