Field help (CCEBUD) 

When this field is checked, a budget can be build in this dimension. Using some dimensions can thus be reserved to the analytical accounting.

Associated with the analytical accounts, the dimensions are the reference element in the analytical management (posting of accounting documents) and budgetary management (entry). They are mainly used to carry out comparisons between the "actual" and the "budget".
It can nevertheless be decided to restrict the entry of budget elements in an analytical dimension.
