This video shows the steps involved to code merge a new Retail Sdk into your current customization branch. In this case, I am updating my AX 7 RTW Retail Sdk (with customizations) to the AX 7 Update 1 Sdk. Same steps apply if you snap to a hotfix or to another update. It is a good practice to use a mirror branch as it makes code merges much easier. The update of the mirror branch is a prerequisite for this step, and was shown in a separate video.
