In order for a group of companies to use dimensions on intercompany transactions, they must agree on a set of dimensions to use as a common reference. To define the IC dimensions that you and your partner companies will use to make intercompany transactions, follow this procedure:
Open the 
IC
Dimensions window.
Enter each dimension on a line in the window. If your IC dimensions will be similar or identical to your company dimensions, you can fill in the window automatically by clicking Functions, Copy from Dimensions, and then you can edit the resulting lines.
You can export the IC dimensions to an XML file for distribution to your partner companies.
Click Functions, Export...
Specify the file name and the location where you want to save the XML file and then click Save.
Before you can use the intercompany dimensions, you need to map intercompany dimensions to your company's dimensions.
