Need to integrate invoice document from external invoicing system to SAP ERP6 FI

[laurie_mcginley]

We are moving our real estate (re-fx) functionality to a different external system. It will generate the invoices for the contracts (contract conditions). We need to send that data for the invoice to the SAP ERP6 FI system.

(Basically we are keeping the SAP FI/AR functionality in SAP but need to get that financial data about an invoice to and from the SAP system to our new 3rd party system.

Is there an integration or BADI/BAPI for this?

Thanks

Take care

Old but still a good starting point

IDoc Interface: EDI Application Scenarios (BC-SRV-EDI) (consolut.com)

for the technical background ALE Quick Start (consolut.com)

You can find the old printdocu in SAP® Online Help PDFs - consolut

SAP IDOC Tutorial: Definition, Structure, Types, Format & Tables (guru99.com)

May be another hint, you will find a lot of blogs which points to the existing user exits like this blog INVOIC IDoc processing of Intercompany billing (IV) | SAP Blogs

But you should avoid all this single exits to manipulate the data, there are two central BADIs for manipulating IDOCs

IDOC_DATA_MAPPER

IDOC_DATA_INSERT

if you implement them in the correct way you will have all changes logged and you can have all your code in one class with different a structure for your needs. This is far better than searching in zillions of different function modules.

Kind regards

You can transfer invoice data via IDOC between systems.

Ok, thanks. Not having used IDOC before, is there some additional documention you can point to I'd find helpful?

Thanks 😉
