Capacity leveling is used in various areas of a company and at different planning levels with the following objectives:

- High capacity load 
- Adherence to dates 
- Short lead times 
- Low stocks

The objectives of capacity leveling include:

- Leveling overloads and under loads at work centers 
- Achieving optimum commitment of machines and production lines 
- Selection of appropriate resources

Show here is an example on how to customize the Capacity Leveling Profile.

Define time profile in OPD2.

Assuming you want to create a time profile for 2 months.

                                        Entry Type    Start Date     End Date
Database Read Period            J                -3                   3

The database read period specifies the period in which capacity requirements are read 
from the database. All requirements are accessed which are partially or completely 
within the database read period.

Evaluation Period          G              -1           60

The evaluation period specifies the period over which data is formatted and displayed. 
The evaluation period must lie within the database read period.

Planning Period            G              -1           60

The planning period defines the period in which the SAP system can carry out planning. 
The planning period is smaller than or equal to the evaluation period. You cannot move 
operations outside the planning period. Equally, when automatic finite scheduling is 
carried out for an operation the system only searches for a new date within the planning 
period.

Dispatch of backlog        G         Backlog dispatch Date = 0

The date for dispatching the backlog is of importance in period-related planning.
You use the date for dispatching the backlog to determine the date backlogs are to be 
allocated.

The following types of entry are available:

Actual date specifications 

These date specifications (for example, calendar day, calendar year) are only useful in 
the profiles in exceptional cases.

Relative date specifications 

These date specifications (for example, number of calendar days, number of calendar years) 
are always calculated from the current day.

For every period, you can specify in what form you want to enter the date by using the 
respective field "Type of entry". 

Define the strategy profile in OPDB.

In this menu option you define strategy profiles to control capacity leveling with the 
planning tables.

You can copy the standard strategy profile like SAPSFCVER1 or SAP_T001.

Assuming you copy the strategy profile to ZAPSFCVER1 ticking the followings:-

1.   Dispatch at earliest point in time.
2.   Change production version on error.
3.   Cancel dispatching due to error.
4.   Use operations floats.
5.   Use float before production.
6.   Use float after production.

and copy the strategy to ZAP_T001 ticking the Change Planning direction.

Define the Overall profiles in OPD0.

The overall profiles are used as follows to control capacity planning:

If you select the menu options: 
Capacity planning -> Leveling -> Work center view -> Planning table, then the profile 
SAPSFCG001 is processed in the standard version. 

You can change the profile, but the SAP sub-profiles should remain unchanged as far as 
possible.

You can define your own profiles and allocate them to particular users by means of user 
parameters. (See user parameters CYA -> CYX) 

For example, when you access the planning table enter using the application menu 
"Capacity planning" -> Leveling -> Work center view -> Planning table 
the user parameter "CYA" is operative.

You can select any overall profile you like by entering via the application menu 
"Capacity planning" -> Leveling -> Variable. 
 

Your details of the profile can be as follows:-

Profile                      ZONLINE         ZBACKGRD
Selection profile       SAPSFCS005    SAPSFCS001
Control profile         SAP__C001       SAP__C002
Time profile             ZTIME                SAP__Z002
Evaluation profile     SAP__A001       SAP__A001
Strategy profile        SAP__T001        ZSTRATEGY
Period profile           SAP__P002
Planning table profile                           SAPSFCL010
Prof. Plan tab (tab)   SAPSFCR011
List profile                SAPSFCI001     SAPSFCI001
