In your extension, the name of each new application object (table, page, codeunit), must contain a prefix or suffix. This rule applies to all objects. You can use the Caption values for what you decide to display to the user. When you modify a core Dynamics 365 object using a Table Extension or Page Extension, the prefix/suffix must be defined at the control/field/action/group level.

Declare your objects with a prefix as shown in the following examples.

Table

table 70000000 MyPrefix Salesperson

Page

page 70000000 MyPrefix Salesperson

Page Extension

actions
{
    addafter(ApprovalEntries)
    {
        action(MyPrefix Vacation)

Codeunit

codeunit 70000000 MyPrefix Salesperson

Benefits

There are two good reasons to why you may want to proactively use a prefix or suffix:

1. App A and App B both use the same field name (for a native Dynamics 365 table) of FAB Salesperson Code. The partner for App B already has the prefix/suffix reserved. A customer wants to install both apps but cannot due to collision of field name. App A will have to reserve a different unique prefix and submit an updated version of their app.

2. Dynamics 365 developers want to use the name of Salesperson Code. App A (published for months), already has that field name. Microsoft will require the app to prefix its field names by submitting an updated version of their app.

General rules

• The prefix/suffix must be at least 3 characters
• The object/field name must start or end with the prefix/suffix
• If a conflict arises, the one who registered the prefix/suffix always wins
• For your own pages/tables/codeunits, you must set the prefix/suffix at the top object level
• For pages/tables in the base application of BC that you extend, you must set the prefix/suffix at the top object level
• For pages/tables of BC in the base application that you extend, you must also set at the control/field/action level
• Use the AppSourceCop tool to find all missing prefixes and/or suffixes. Configuration options for this tool can be found here. The Rules section explains the different checks the cop will do. For prefix/suffix detection, refer to the Configuration section. It explains how to set your prefix in the AppSourceCop.json file.
