Project history
Target of this project was to rewrite large, custom Dynpro (SAP GUI) application to utilize new features of SAP/HANA and RAP (RESTful Application Programming model). On the presentation layer, the rewrite process was conducted in parallel, for new Fiori based and the old SAP GUI interface. Business logic was common for both and was realized with HANA CDSs. My task was to rewrite the Dynpro logic to utilize Object Oriented MVC (Model View Controller) paradigm and consume CDSs as data source for the Model layer. As View layer enhanced BUS framework was utilized.
Data migration from obsolete non-SAP HR system. System integration, reporting.
Design, development, test, implementation & support of SAP ABAP / PI interface
for automatic SAP LE (Shipments) and TM, events send & receive via a SHIPPEO REST web-service.
Interface was utilizing PI adapters (REST for web-service) and ABAP Proxy and IDoc on ERP side. For PI message mapping XSLT was used.
Design, development, test, implementation & support of SAP ABAP / PI interface
for automatic shipment label creation in PDF upon customer invoice creation in SAP LE.
Interface was utilizing PI adapters (HTTP_AAE for web-service) and ABAP Proxy and IDoc on ERP side.
For PDF generation, a combination of XSLT and Java PI mapping was used.

Exchanged messages cover, among others: Purchase Orders (SAP=>P2P), Goods Receipts (SAP=>P2P), Invoices (P2P=>SAP), Invoice PDF scans (P2P=>SAP ArchiveLink).
Interfaces were utilizing PI adapters (REST, SFTP) and ABAP Proxy on ERP side.
To control message flow, for each business document (PO, GR, IV) a dedicated monitor was developed in SAP.
Design, development, test, implementation & support of EDI communication. Used EDI standards cover EDIFACT & ANSI X12. Message types: INVOIC, ORDERS, ORDRSP, DELFOR, DESADV. PI adapters: SFTP, AS2. On SAP PI side B2B add-on was used. XSLT and graphical mapping was used in PI.
