Defining the Lines in a Planning Type 
Having created the initial definition for your planning type (see
Creating a Planning Type), you can now define its lines.
If your planning type is dual-level and level-by-level planning is defined for the information structure, you create lines, define line attributes, assign key figures, and define macros at both owner and member level.
The initial planning table contains ten blank lines. You can assign key figures and some other types of data to these lines.
Assigning a Key Figure to a Line
To assign a
key figure from the information structure to a line:A dialog box appears inviting you to choose a key figure.
The selected key figure now appears in the planning table.
Creating Lines in a Planning Type
You can add extra lines in several ways:

Only key figures are saved in the information structure; other data is calculated or read into the planning table at runtime.
A blank line appears at the bottom of the planning table.
A blank line appears at the point in the planning table where you positioned your cursor.
This causes lines to appear containing all key figures from the information structure. You can delete any lines you do not need.
A line is inserted below the current line. In the planning table, the actual values of this key figure will be displayed here, that is, the values from version 000. You cannot enter or overwrite values on this line.
This line is useful for comparing planned data with actual data. In retail, for example, you can use it to track open-to-buy.
A line is inserted below the current line. In the planning table, the actual values of this key figure from the previous year will be displayed here. You cannot enter or overwrite values on this line.
This line is useful for comparing planned data with actual data from the previous year.
A line for external data is inserted below the current line. You can write your own coding for function module EXIT_SAPMMCP6_001 to display data¾for example, auxiliary data ¾on this line in the planning table. The function module will be called when you create or change a plan of this planning type.
Lines to show the values of events for this key figure are inserted. See also Assigning an Event to a Planning Type.
Defining Line Attributes
Each line has certain attributes that define how its contents are processed and displayed in the planning table.
To define the attributes of a line:
The Line Attributes dialog box appears.
Standard text indicates that the text comes from the key figure in the information structure.
Freely defined text indicates that the text is entered by the user (see step 2 above).
Planning object indicates any characteristic value, such as a material number or a work center capacity.
Planning line indicates that you want to be able to plan, that is, overwrite the figures in this line.
Output line indicates that you want to be able to see, but not enter or change, values in this line.
Text line indicates that the line contains a text but no numerical values.
Auxiliary line indicates that the line acts, for example, as an intermediate step, but is displayed only in the planning table definition (Goto ® Format ® Definition) and not in the planning table (Goto ® Format ® Layout).
