Handling Merge Conflicts

  • [アーティクル]

When you merge application changes by running the Merge-NAVApplicationObject cmdlet or the Update-NAVApplicationObject cmdlet, the differences are applied automatically if it is possible. However, when conflicts are detected, they are captured in CONFLICT files. The CONFLICT files clearly identify where two parties such as you and Microsoft have changed the same object or parts of it. You can open a CONFLICT file in Notepad, for example, and see the type of conflict, such as a code conflict or conflicting object property values. By clearly identifying the conflicts in this manner and automatically merging all other changes, you can more easily resolve the conflicts.

Identifying Conflicts

The CONFLICT files describe differences that were not automatically merged. This includes conflicting code modifications, property settings, and application code. Each conflict is clearly marked in the corresponding application object text file in the RESULT folder. A copy of the files in ORIGINAL, MODIFIED, or TARGET that caused the conflict is added to subfolders to the RESULT folder. For example, if you run the Merge-NAVApplicationObject cmdlet on three different versions of codeunit 1, and a conflict is found, the RESULT folder will contain the following:

Folder File name Description
RESULT COD1.CONFLICT Describes the conflict, such as a code modification in a function.
COD1.TXT The merged application object that has the conflicting code clearly marked.
ConflictModified COD1.TXT The conflicting application object from the MODIFIED version.
ConflictOriginal COD1.TXT The conflicting application object from the ORIGINAL version.
ConflictTarget COD1.TXT The conflicting application object from the TARGET version.

Because the CONFLICT files describe the conflicts, you can import the merged text files into the Dynamics NAV Development Environment and resolve the conflicts there. Alternatively, you can use an external three-way merge tool to analyze the conflicts.

In most cases, the text files that contain the merged application objects clearly identify where the conflict is. The following code example illustrates an object that has a conflict.

PROCEDURE ApplicationBuild@3() : Text[80];  
BEGIN  
  {>>>>>>>} ORIGINAL  
  EXIT('35473-ORIGINAL');  
  {=======} MODIFIED  
  EXIT('35978');  
  {=======} TARGET  
  EXIT('35473');  
  {<<<<<<<}  
END;

In this example, the ApplicationBuild function is different in all three versions of codeunit 1 that you tried to merge. If you import this file into the development environment, it will not compile. To resolve the issue, removed the unwanted code, including all brackets {}. You can do this, for example, in Notepad, a three-way merge tool, or in the development environment. Use the source files in the subfolders in the RESULT folder to learn how to resolve the conflict.
