This is what happens in the video
If you work with dimensions in Business Central, you can attach default dimensions to most of your master data tables, including vendors. When you set a default dimension on a vendor, it follows automatically onto new purchase documents and carries through to the posted documents, unless you change it on the open document first. This saves you from entering the same dimension values manually every time you create a purchase document for that vendor.
Where to set up default dimensions on a vendor in Business Central
To attach a default dimension to a vendor, open the vendor card. From there, click the Vendor menu and select Dimensions. This opens the list of dimensions configured for that vendor.
In the example here, the vendor is already set up with a value in the Project dimension of 51. You can add other dimensions as well. There is also a Department dimension available, so you can select Department and pick a value from the list of departments. Once you save it, that value becomes a default dimension on the vendor.
How default dimensions flow to purchase documents and posted entries
When you create a new purchase document for a vendor that has default dimensions, those dimension values follow the vendor onto the document. They then carry through to the posted documents when you post.
The default values are only a starting point. If you change a dimension value on an open document before posting, your change is what gets posted. The default simply gives you a sensible value to begin with, so you don’t have to type it in every time.
