Preface – This post is part of the ABAP Programs series.
In this article, you will learn how to get location of a pdf file, how to convert pdf to xstring in abap and how to use GUI_UPLOAD Function Module to perform pdf upload in ABAP.
Table of Contents
To Upload a PDF using ABAP Program, you need to get the location of the file and the pdf file. You need to convert this file in XSTRING. In the code shown below, we have used GUI_UPLOAD Function module to get data in an Internal Table.

Initially, we have defined variables in three parts:
- Parameter: p_file that is of type string and will store location of file
- gs_store_file, gt_content, len, xstr_content: data related to file i.e. where file will be store, how the content will be stored, length of the file and type of content.
- Third set of variables deals with the PDF file content detail. These details are the one that is stored in a table and whose type internal table is created above “gs_store_file”.
Function Module used:
What exactly to store in the table via upload in ABAP:
- PDF file location
- PDF file name
- File type
- File X-STRING Data [This is the actual file that is converted in x-string]
Later on we have called different Function Modules. We have added respective comment in the code itself.
