GTC. 
In short, the Interface Structures allow you to describe the format of import files, whereas you can use Mapping (Positions) to define the transformation of source positions to GTC form fields and to specify simple calculation logic.
Interface Structure
The menu item Interface Structure contains a list of all structures already defined in the GTC with their most important properties. The interface structure can be edited using the Edit icon (pencil). 
The format of the import file can be described here, that is: the file type and the fields are assigned to certain positions of the import file.
On addition to the file-based import and export, GTC currently supports the following standard technologies:
- Web Services
- SAP RFC

(RFCs) are a proprietary SAP protocol for data exchange with SAP systems. The use of RFCs requires that a corresponding function module exists on the SAP side. In this way, balance sheet and P&L statement data can be retrieved directly from SAP and processed further, which leads to increased data security and requires less effort on the part of the GTC users.
NEW
As an alternative to the HB / StB deviation, the import of the tax balance sheet can also be defined. Since the GlobalTaxCenter only stores the difference, it must be calculated from the tax balance value and the HGB value during the import.
Mapping (Positions)
During the Mapping you describe how a source position is mapped to the GTC target fields. The Export icon (red arrow) can be used to download the template for the mapping file. This is an Excel file that you can edit locally. The filled out file can be uploaded using the Import button (green arrow).
The mapping supports a number of mappings to GTC positions (possibly also with simple calculations and GTC-specific instructions). Please contact AMANA for more details on these functions.
Interfaces within the tax portal
There are predefined interfaces between the individual components of the tax portal, which can be used to avoid multiple entries of data. The following table provides an overview of these interfaces.
