Rounding to Sales Unit in GATP

Question

HI! All
We are in process of implementing GATP and we have a requirement of rounding the confirmed quantity in APO.
The standard Library says that it can be achieved provided you carryout availaibility check from CRM system & you should have ECC defence system.
We dont use CRM nor we have ECC defence.
Can rounding be achieved while carrying out availaibility form a normal ECC system.
Has any body tried it.
Please no links & theoritical answers.
Thanks in Advance

Hi
To perform rounding successfully, you must make the settings described Bellow
Procedure
Settings for Rounding to Pack Sizes
Settings in SAP SCM
●     Settings in SCM Basis
a.Define a number range for the packaging specification. 
For more information, see the Implementation Guide (IMG) for SAP SCM under SCM Basis ® Packing ® Packaging Specification ® Define Number Range for Packaging Specification.
b.Make the following settings for determining packaging specifications:
i. Define a field catalog.
Note that you must transfer customer-specific fields to the field catalog for Global ATP. In addition, you must implement the Business Add-In (BAdI) /SAPAPO/ATP_RND for customer-specific fields.
ii. Define condition types for the PAK application and the PS usage. Create access sequences, accesses, and condition tables.
iii.       Define a determination procedure.
For more information about determining packaging specifications, see the IMG for SAP SCM under SCM Basis ® Packing ® Packaging Specification ® Determination of Packaging Specifications.
●     Settings in SAP APO
Define one or more packaging specifications. To define a packaging specification, on the SAP Easy Access screen, choose Advanced Planning and Optimization ® Global ATP ® Environment ® Packaging Specification ® Maintain Packaging Specification.
Make the following rounding settings for the packaging specification you created:
○     Header Information for the Packaging Specification
Choose one of the following rounding methods:
■      Pack-size-oriented rounding method
The pack-size-oriented rounding method rounds the demand to the next largest or next smallest pack size. Your settings for the packaging specification levels determine rounding.
■      Demand-quantity-oriented rounding method
The demand-quantity-oriented rounding method rounds the demand according to the rounding limits that you specify here. Enter the upper and lower rounding limit (as a percentage of the demand quantity or the monthly demand). The upper and the lower rounding limits are not related to the pack sizes.
Define the minimum quantity. This represents the smallest possible rounding result.
○     Contents of the Packaging Specification
Enter the product, the smallest quantity for the unit, and the unit of measure. The product is not the product to be checked; it is only a reference product for the calculation of the quantity.
○     Packaging Specification Levels
The levels of a packaging specification represent the different pack sizes for the product, such as package, box, and pallet.
i.       Define one or more levels for the packaging specification.
ii.       Specify which level is the smallest pack size.
iii.       If you have chosen the pack-size-oriented rounding method, you can specify either the upper and lower rounding limit (as a percentage of the pack size) or the rounding direction for each level that you have defined after the level with the smallest pack size.
You can specify a rounding direction for the level that represents the smallest pack size, but not rounding limits.
If the demand quantity is smaller than the quantity that is contained in the smallest pack size, the system always rounds up (to the smallest pack size). Confirmed quantities can be rounded to zero.
Each additional pack size can only be defined as a multiple of the previous pack size. You can define 1, 10, and 30 as pack sizes in a packaging specification, for example, but not 1, 10, and 25.
●     Settings in Global ATP
Create a check mode and specify the rounding procedure that you want the ATP check to use as a basis for rounding. In SCM Basis, you have defined the rounding procedure as the determination procedure.
Create check instructions and activate the rounding procedure. After you have activated the rounding procedure, Global ATP rounds according to the specified rounding procedure.
Settings for Rounding to Sales Units
Settings in SAP ECC
In Customizing for SAP ECC Enterprise Extension Defense Forces & Public Security (EA-DFP), activate rounding by setting the Only Complete. indicator. By using the advice code, you specify that only complete packs are to be delivered.
Settings in SAP SCM
Define sales units in the product master on the Units of Measure tab page. To call the product master, on the SAP Easy Access screen, choose Advanced Planning and Optimization ® Master Data ® Product ® Product.
