The Gantt chart in the production modules is primarily used to show the operations scheduling from various angles, for example for one particular production file, for multiple production files, for particular orders, or for one particular part. Changes made elsewhere in Isah, such as changes to the capacity, the start or end date or the quantities, will become visible after you have recalculated the planning figures.
It is not possible to add new lines to, or to change the content of, lines in the Gantt chart of the production modules. The purpose of the Gantt chart on this form is to show planning data that are managed elsewhere. In this Gantt chart, you can only make changes that directly relate to the planning (such as moving, extending or shortening an operation, or specifying a successor).
