What is it significance and what is the process for GATP and tell me the best practices for GATP.
---
GATP stands for Global Available To Promise. It is part of SAP SCM-APO tool.
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.
It is a tool by which you try to maximize your servicing capacity to the customer by using different methods of GATP.
e.g. You define if a customer ask for product A if A is not available you can give him B or C or D or ALL (Functionality product substitution), if these products are not available in asked location, system will look for other locations (Functionality product substitution).
If nothing is available, system trigger production (using Available To Promise).
In short how it helps is, by reducing customer
demand loss by increasing the serviceability.
ATP Versus GATP
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.
