Enter a restriction code at this level or set one up at the dimension-dimension, account-account, or account-dimension Restriction code level.
To ensure the coherence of postings, you can forbid the entry of associated accounts with specific dimensions, accounts with other accounts, or dimensions with other dimensions.
The principle is to define "forbidding code" pairs that are not compatible when posting. When an account and a dimension have incompatible codes, they cannot be used together for posting the same entry line.
