function import - Details

  Key Concepts: 
  Function import is a feature of the SAP Platform Foundational Capabilities (LOD-SF-PLT) that allows users to call a remote function module from within an ABAP program. It enables users to access data from external systems, such as databases, web services, and other applications. Function import also allows users to execute remote functions without having to write any code. 
  
  How to use it: 
  To use function import, users must first create a function module in the external system. This function module must be accessible from the SAP system. Once the function module is created, users can call it from within an ABAP program using the CALL FUNCTION statement. The parameters of the function module must be specified in the CALL FUNCTION statement. 
  
  Tips & Tricks: 
  When using function import, it is important to ensure that the parameters of the function module are specified correctly in the CALL FUNCTION statement. If any of the parameters are incorrect, the function module will not be executed correctly and may return unexpected results.
