How to upload Excel to SAP(using ABAP) Posted on: December 30, 2019 | By: Pawan Kesari – 30 Comments ABAP code to upload XLSX file to SAP using ABAP. The method shown in the blog will work in SAP GUI and Webgui (program launched from Fiori Launchpad). This approach will also work with OData. Code is based on class CL_FDT_XL_SPREADSHEET which can be instantiated using the file name and excel file in XSTRING variable. This processing of file as XSTRING is particularly useful in case of Fiori Apps, OData CREATE_STREAM method pass uploaded file already in XSTRING which can be simply passed on to class CL_FDT_XL_SPREADSHEET constructor. After instantiating the class get list of worksheets in the file using IF_FDT_DOC_SPREADSHEET~GET_WORKSHEET_NAMES. Method GET_WORKSHEET_NAMES returns internal table. In most of the case, you would read the first worksheet name and call method IF_FDT_DOC_SPREADSHEET~GET_ITAB_FROM_WORKSHEET with worksheet name to get data in a dynamic internal table. H
