2.1.1.4 Mapping and extraction class

The class of product we offer for issued invoices to execute their mapping is: /EDGE/CL_EI_IT_FI_ISS_INV_MAP.

The class for extracting the data directly from the SAP tables is: /EDGE/CL_EI_IT_FI_GET_DATA.

If we want to change any mapping or any extraction from our implementation we'll have to create a new Z class that inherited from these classes inheriting from /EDGE/CL_EI_IT_FI_ISS_INV_MAP in the case we want to change the mapping and from /EDGE/CL_EI_IT_FI_GET_DATA if we want to change the extraction.

 

Example of inheritance for the mapping class

 

We inherited from the class /EDGE/CL_EI_IT_FI_ISS_INV_MAP.

We will redefine the method of the class we want to change.

 

Once the class is created, we have to parameterize it in the table /EDGE/EI_IT_CLCU
