Availability Check Using External Systems 

Use

If you do not use an SAP Advanced Planner and Optimizer (SAP APO) or SAP R/3 system for material resource planning but use an external (non-SAP) ATP system instead, you can link this external system to CRM Enterprise to carry out availability check or obtain availability information.

For more information, see Availability Check and availability information.

Integration

A framework for Business Add-Ins (Add-Ins) is provided for the integration between CRM Enterprise and an external ATP system. The Add-Ins are located in the Implementation Guide (IMG) for Customer Relationship Management at Basic Functions ® Availability Check ® Availability Check / Info Using External ATP System.

You need to implement the Add-Ins that contain all the necessary logic to access the required ATP system and to provide it with the necessary input data.

Features

For information on how availability check works, see Availability Check Using SAP APO.

Restrictions

The following restrictions apply:

●     You must decide for each client whether you want to carry out availability check or obtain availability information. A combination of the two functions within one client is not possible.

●     These Add-Ins are designed for a single backend and a single ATP system.
If you need to use several external ATP systems, you must provide a determination logic for distribution. When the results from the ATP check are transferred back to CRM Enterprise, it must look as though the data was processed by only one ATP system.
