Plant Master Data
As described in section Branch - Organizational Unit, plants must be linked to branches. More than one plant can be assigned to a branch.
You can allocate a plant to a branch by choosing the customizing path Allocate branch - plant.
Before the plant can be allocated to a branch, it is necessary to assign the plant to a company and to maintain the CGC company.
If either the plant is not assigned to a company code or the CGC company is not specified, the field to enter the branch is not available for input.
