Hi Pooja,

GATP is like promising to customer demands based on some predefined availability checks on your existing stocks. It uses ATP rules to decide whether the customer demands can be confirmed against the available stocks.

you can get the best practices for GATP by SAP on the below link. It should also give you idea for the configuration part and how it is done.

Dear Pooja,

ATP functionality is already there in R/3 but with limitations :-

1.ATP-Availability check in ERP is limited to single location.

2.Product Substitution is manual and it is limited to single material substitution.

3.Production cannot be called from ATP check for a MTS product.

4.No simulation.

Global ATP checks the entire network( other plants) , product / material substitutions defined in the condition and also production from alternative location based on the advanced functionality called Rule based ATP

+ Alternative Product

+ Alternative Location

+ Production (Alternation PPM).

You can also call production while creating a sales order and if the sales order is not fully confirmed or call production directly , based on the available capacity ,a planned order can be created and the delivery proposal can get the confirmation date.

Dear Pooja,

GATP stands for Global availaible to promise. Its is part of SAP SCM-APO tool.

its quite big question to address it in forum but ill try to give some basic details, rest go through the Standard library.

link http://help.sap.com/saphelp_scm50/helpdata/en/12/3dfd81126e1c448c870f335f11d016/frameset.htm goto GATP

It is a tool by which you try to maximise your servicing capacity to the customer by using diffrent methods of GATP.

e.g. You define if a customer ask for product A if A is not availaible you can give him B or C or D or ALL ( Funtionality product substitution), if thses products are not availaible in asked location look for other locations (Funtionality product substitution).

if nothing is availaible trigger production( using Capable To Promise).

In short how it helps is, by reducing custome demand loss by increasing the servicebility.

Hope this helps you.
