Hi Ajit,
<b>Schedule line</b>
The division of an item in a sales document according to date and quantitiy.
For example, if the total quantity of an item can only be delivered in four partial deliveries, the system creates four schedule lines and determines the appropriate quantities and delivery dates for each schedule line
<b>Schedule Line Categories</b>
The SAP System can only copy those items of a sales document to a delivery for which schedule lines exist. Control of the schedule lines depends on the schedule line category.
You have the following options for defining your own schedule line categories:
1)change an existing schedule line category.
2)copy an existing schedule line category and change it according to your requirements.
3)create a new schedule line category.
<b>Schedule line category</b>
The schedule line category is has an alphanumeric key with a maximum of two characters as well as a textual description.
<b>Business data</b>
Delivery block
When you define a delivery block for a schedule line category, this specification is copied to the schedule line. The schedule line is then blocked for all delivery types that are allocated to this delivery block. Information on the assignment of delivery blocks to delivery types can be found in the section "Define blocking reasons in Shipping".
Movement type
Here, you specify a movement type for posting quantities and changes in value to inventory accounting. The movement type is only relevant to items or schedule lines which result in a stock movement.  It is not relevant, for example, for:
inquiry items
quotation items
order items without inventory management
Do not specify a movement type for goods issue for the schedule lines for returns items. Instead, specify a goods movement for the return delivery, thus for goods receipt.
Item relevant for delivery
Schedule lines for order items are relevant for delivery if a physical goods delivery is to be made. In contrast to this, schedule lines for quotation items are not relevant for delivery. You indicate the appropriate schedule line category here.
Requirements
Transfer of requirements can be controlled at schedule line level. Transfer of requirements is carried out for the transaction if you set the indicator. The indicator corresponds to the settings for the transfer of requirements for each schedule line category and can also be set there.
Availability
The availability check can be controlled at schedule line level. An availability check is carried out for the transaction, if you set the indicator. The indicator corresponds to the settings for the availability check for each schedule line category and can also be set there.
Purchase order/purchase requisition
A purchase requisition can be automatically created for a schedule line by the SAP System. For this to occur, you must enter the following data here:
type of purchase order
type of purchase order item
type of account assignment
type of document category
At the moment, only purchase requisitions can be created automatically.
Transaction procedure
Incompletion procedure
The incompletion procedure that you enter here, specifies which fields must be completed by the user. A corresponding entry is created in the incompletion log for fields that are not filled during document processing.
Recommendation
If you define your own schedule line categories, the keys should start with the letter Z since SAP leaves this range free in the standard system.
If you define your own schedule line categories, you should copy similar schedule line categories that are defined by SAP and make the appropriate changes.
In this case, all the specifications of the already existing schedule line category are copied, including the allocation to the item categories. In particular, the data for example concerning incompleteness, the availability check and document flow, which you do not edit in this menu option, is copied.  In this way, you can test your new schedule line categories in respect to the settings that have been made without having to edit the other menu options.
When copying sales document types, item categories and schedule line categories, the SAP System automatically creates a log with the copied data. Using the log, you can check whether all the copied data applies to your schedule line category or whether you must make changes.
Default settings
In the standrad SAP R/3 System, the key of the schedule line categories contains the following information concerning its usage:
First character of the key usage
   A inquiry
   B quotation
   C sales order
   D returns
Second character of the key usage
   T no inventory management, e.g. services
   X no inventory management with goods issue
   N no planning
   P MRP
   V consumption-based planning
Actions
1. Change the schedule line categories according to your requirements if you only need to make minor changes to the existing schedule line categories. Minor changes are parameters which have no controlling character. A minor change could be a changed description.
Define new schedule line categories if you need to make further changes.
2. Maintain the detail screen according to your requirements.
You can, for example, allow the SAP System to create purchase requisitions automatically for particular schedule line categories.
