What is Combining Data with Calculated Fields in Dynamics 365?

In Microsoft Dynamics 365, a calculated field is a powerful no-code feature that lets you automate simple data manipulation. To combine data from two fields using calculate field dynamics 365 means creating a new field whose value is automatically generated by joining the data from two or more other fields. This is most commonly used for creating composite fields like a “Full Name” from “First Name” and “Last Name” fields.

This functionality is not limited to just names. It’s used to create unique IDs, compound addresses, or descriptive labels from existing data points, streamlining data entry and ensuring consistency across the system. The core function used for this is `CONCAT`, which concatenates, or links, strings of text together.

The Formula to Combine Data from Two Fields in Dynamics 365

The primary function to combine data from two fields in a Dynamics 365 calculated field is `CONCAT`. The function takes two or more text arguments and joins them into a single string. You can mix field values and literal strings (like spaces or hyphens) as arguments.

The basic formula is: CONCAT(source_field_1, "separator", source_field_2)

Formula Variables
Variable	Meaning	Unit	Typical Range
`source_field_1`	The first field you want to combine (e.g., ‘firstname’).	Text String	Any text up to the field’s length limit.
`"separator"`	A literal text string to place between the fields (e.g., ” “, “-“, “, “).	Literal String	Typically 1-3 characters.
`source_field_2`	The second field you want to combine (e.g., ‘lastname’).	Text String	Any text up to the field’s length limit.

Practical Examples

Example 1: Creating a “Full Name” Field

This is the most common use case to combine data from two fields using calculate field dynamics 365. It improves user experience by displaying a complete name while keeping the first and last names as separate data points for sorting or integration.

Input 1 (First Name): “Maria”
Input 2 (Last Name): “Campbell”
Separator: ” ” (a single space)
Formula: CONCAT(new_firstname, " ", new_lastname)
Result: “Maria Campbell”

Example 2: Generating an “Apartment-Suite” Reference

Imagine you manage a property database and need a quick reference for a building and its suite number. A calculated field can create this instantly.

Input 1 (Building Name): “Northwind Towers”
Input 2 (Suite Number): “4B”
Separator: ” – Suite “
Formula: CONCAT(new_buildingname, " - Suite ", new_suitenumber)
Result: “Northwind Towers – Suite 4B”

How to Use This Dynamics 365 Field Combination Calculator

This calculator simulates the behavior of a real Dynamics 365 calculated field. Follow these simple steps:

Enter First Field Value: Type the text for your first source field in the “Field 1 Value” box.
Enter Second Field Value: Type the text for your second source field.
Define the Separator: In the “Separator” box, enter any characters you wish to place between the two values. A space is provided by default, but you can use a comma, hyphen, or any other text.
View the Result: The “Calculated Field Result” box will update in real-time, showing you exactly how Dynamics 365 would combine the data. The intermediate values are also shown to clarify how the final string is constructed.
Reset or Copy: Use the “Reset” button to clear all fields or “Copy Result” to copy the output to your clipboard.

Key Factors That Affect Calculated Fields

When you combine data from two fields using calculate field dynamics 365, several factors can influence the outcome and behavior:

Data Types: The `CONCAT` function is designed for text fields. If you include number or date fields, they will be converted to text, which might lead to unexpected formatting.
Field Length Limits: The target calculated field has a maximum length. If the combined string exceeds this limit, the data will be truncated, leading to incomplete text.
Use of TRIM: Often, source fields contain leading or trailing spaces. Using `TRIMLEFT` or `TRIMRIGHT` on the source fields within the `CONCAT` function can help create cleaner output.
Conditional Logic: You can wrap your `CONCAT` function inside an `IF` statement. For example, only combine the fields if both contain data.
Performance: While efficient, calculated fields are computed in real-time on data retrieval. Overusing complex calculated fields on lists with thousands of records can impact view load times. Check out our guide on optimizing Dynamics 365 performance.
Null Values: If one of the source fields is empty (null), `CONCAT` will simply treat it as an empty string. It will not cause an error.

Frequently Asked Questions (FAQ)

Can I combine more than two fields?: Yes, the `CONCAT` function accepts multiple arguments. You can nest them or list them, for example: `CONCAT(field1, ” “, field2, “, “, field3)`.
What happens if I combine a text field and a number field?: The number field will be converted to a string before being concatenated. For example, combining “Order #” and the number 12345 results in “Order #12345”.
Can I use a calculated field in a workflow?: Calculated field values can be read and used by workflows and business rules, but their calculation logic is independent. For more complex scenarios, consider using a tool like business rules dynamics 365.
Is there a difference between a calculated field and a rollup field?: Yes. A calculated field operates on columns within the same record (or a parent record). A rollup field aggregates data from related child records, such as counting the number of contacts for an account.
How often does a calculated field update?: The value is calculated in real-time whenever the record is retrieved (e.g., when you open a form or view a list). The value is not stored in the database.
Can I sort views based on a calculated field?: Yes, you can sort and filter views using calculated fields just like with regular fields.
What if my text contains quotation marks?: In the Dynamics 365 formula editor, you must escape quotation marks within a literal string with a backslash (`\”`). For instance, to include the text `12″ pipe`, your string would be `”12\” pipe”`.
Can I perform a dynamics 365 concatenate fields operation with fields from a related entity?: Yes, you can reference fields from a parent record (a record linked via an N:1 relationship). For example, on a Contact record, you could create a calculated field that combines the contact’s name and the parent Account’s name.
