Certainly! To read a PDF file from the presentation layer (local file system) into an internal table in SAP ABAP, you can follow these steps:

1. **Upload PDF File to SAP Presentation Server**:
- Use the transaction `CG3Z` or similar to upload the PDF file from your local system to the presentation server (the application server of SAP system).

2. **Read PDF File and Populate Internal Table**:
- Use the function module `GUI_UPLOAD` to read the content of the PDF file into an internal table. Ensure that the internal table structure matches the content of your PDF file.
- Below is an example code snippet:

DATA: lt_pdf_content TYPE TABLE OF char255,
lv_file_name TYPE string,
lv_path TYPE string,
lv_rc TYPE i.

lv_file_name = 'YOUR_PDF_FILE.pdf'. "Replace with your PDF file name
lv_path = 'YOUR_PATH/'. "Replace with the path where the PDF file is located

CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
filename = lv_path
filetype = 'BIN'
TABLES
data_tab = lt_pdf_content
EXCEPTIONS
file_open_error = 1
file_read_error = 2
no_batch = 3
gui_refuse_filetransfer = 4
invalid_type = 5
no_authority = 6
unknown_error = 7
bad_data_format = 8
header_not_allowed = 9
separator_not_allowed = 10
header_too_long = 11
unknown_dp_error = 12
access_denied = 13
dp_out_of_memory = 14
disk_full = 15
dp_timeout = 16
file_not_found = 17
dataprovider_exception = 18
control_flush_error = 19
OTHERS = 20.

IF sy-subrc EQ 0.
WRITE: 'PDF file uploaded successfully.'.
ELSE.
WRITE: 'Error while uploading PDF file:', sy-subrc.
ENDIF.

3. **Perform Operations on Internal Table**:
- Once the PDF content is loaded into the internal table (`lt_pdf_content` in the example above), you can perform any required operations on the data.

4. **Processing PDF Content**:
- PDF content might not be in a structured format, so you may need to parse it accordingly. This might involve splitting the content, searching for specific patterns, or using third-party libraries for PDF parsing if necessary.

5. **Error Handling**:
- Ensure to handle any exceptions that might occur during the file upload process (`sy-subrc` values).

By following these steps, you should be able to read the content of a PDF file from the presentation layer into an internal table in SAP ABAP and perform necessary operations.

Calling the function module GUI_UPLOAD is obsolete. Instead, you must use the method CL_GUI_FRONTEND_SERVICES=>GUI_UPLOAD.
