A budget weighting code is a coefficient table that allows the monthly allocation of a yearly budget in order to take into account the activity of a company (for instance, the summer closing period).

This budget weighting code is composed of 1 to 10 alphanumeric characters.
It is written in italics beside the account title when the latter has been specified at the level of the account record onto which entries have been posted.
