The items in a sales document are divided into one or more schedule lines. These schedule lines differ from each other with respect to date and quantity.
Different control elements are also defined for the schedule lines. For example, for some schedule lines, material requirements planning is not carried out; for other schedule lines, it is carried out. Also goods receipt, not goods issue, is posted for a schedule line defined in a returns document.
The following graphic provides an overview of some of the item categories which are defined in the standard system.
Schedule Line Category Control
The various schedule line categories are controlled in different ways:
Control Elements for Schedule Line Categories
Different schedule line categories are permitted according to the sales document type and item category you are using. You can use control elements to tailor the schedule line categories to meet the special demands of your installation. You can also define new schedule line categories. Your system administrator is responsible for maintaining the control elements.
The answers to the following questions form the basis for deciding how to define a particular schedule line category:
Determining the Schedule Line Category
The schedule line category depends on the item category of the corresponding item and the material requirements planning type (MRP) of the material. The MRP type of a material is specified in the material master record.
Schedule line categories are proposed automatically based on values set in the appropriate table. You can make some manual changes to the entries in the sales document but you cannot change everything. When you enter another schedule line category, the system checks whether this category is allowed. For information on which schedule line categories are allowed in each case, see your system administrator.
