What is GATP in SAP APO

GATP in the APO Landscape

what is gatp in sap apo•Availability checks are triggered by events in the OLTP system – either the SAP R/3 system or a
legacy system
•An ATP request is sent to SAP APO for all SAP APO-relevant products in the order.
•SAP R/3 allowed product selection and single manual substitution at plant level (one item during the ATP check).
•The ATP check uses PP/DS functions for production.
•By applying rules-based ATP, it is possible to check for alternative products in alternative locations, as well as to consider production across all product levels.
•Global ATP in SAP APO provides information on product availability from the entire supply network.
•The likelihood of making a successful commitment and of having short delivery processing times varies depending on the check method used.
•Global ATP is highly integrated in all SAP APO application components, thus ensuring that the ATP check requirements are fulfilled.

This integration can include the following:
•Demand Planning forecasts can be used as a basis for checks against sales orders when no supply plan exists, such as in a make-to-order environment.
•Supply network plans can be examined at alternative distribution centers and plants, with the option of checking for alternative products.
•Production Planning and Detailed Scheduling (PP/DS) plans can be examined for detailed production plans, and automatic planning can check if an additional production plan can be scheduled for the requirement.


GATP Methods:

1. Basic Method: Product Availability Check

2. Advanced Method: Product Availability Check & Product
Allocation Check

3. Advanced Method: Rules Based Availability (RBA)

4. Advanced Method: Calling Production from ATP check


5. Backorder Processing (BOP)

Availability check tool that allows you to:
•diagnose backorders
•overwrite the committed quantity that resulted from the last availability check.
•Redistribute the confirmed quantity for one or several products over selected customer requirements.
•You can perform backorder processing:
•In the background (batch mode) – including simulation
•As a combination of interactive backorder processing and backorder processing in the background
