Pyrfc: RFCTable type TBL1024

To upload a PDF binary file to SAP I can use an RFC function module. This FM requires two specific parameters:

  • IC_ARC_OBJECT = the document class to define the mime type in SAP (OAC2)
  • IN_CONTENT_LENGHT = IMPORTING data type, is the size of the file
  • IT_CONTENT = IMPORTING table of structure TBL1024, table with the bytes of the file, cut into pieces of size 1024
  • ET_MESSAGES = just a BAPIRET2 table to check on errors (RETURN table)

The function module is successfully executed in the Python program but when I break on the function module to check on the content of IT_CONTENT I can see that the lines of the table are not filled in correctly:

Extraction of the python program call of the FM:

arc_object = "ZZ_PDF" 
content = Arc.get_arc_content(filename)
size = Arc.get_size(filename)
messages = []
result = connection.call("ZZ_UPLOAD_FILE", 
IC_ARC_OBJECT = arc_object,
IN_CONTENT_LENGTH = str(size),
IT_CONTENT = content,
ET_MESSAGES = messages)
messages = result['ET_MESSAGES']
for mes in messages:
     print mes['MESSAGE']

Extraction of the python function Arc.get_arc_content(filename):

def get_arc_content(filename="file.pdf"):
    maxLineLength = 1024
    structure = []
    if filename == '':
        filename = 'file.pdf'
    with open(filename, 'rb') as file1:
        f = file1.read()
        n = 1024
        fl = [f[i:i + n] for i in range(0, len(f), n)]

    content = []
    for line in fl:
        lineapp = {
            u"LINE": line
        }
        print len(line)
        content.append(lineapp)

    return content

The result in SAP is the following for the parameters:

  • IN_CONTENT_LENGHT = 000000007945 (7.8 kb)
  • IT_CONTENT = 8 x 1 lines: (4lines)

The expecting result for IT_CONTENT, checked with FM ARCHIVE_OBJECT_GET, should be something like:

So the problem is that only the first bytes are transferred, the rest are trailing zero's.

Is this related to the fact that I'm doing something wrong, or isn't it possible to cut the binary files properly into chunks of 1024 and transfer them into a table towards SAP. How to use the byte type of SAP in python?

Many thanks for your suggestions/support.

Solution

  • The pyrfc-1.9.4-py2.7-win-amd64.egg solved the issue.

    Seems to be a Windows + PyRFC 1.9.3 version issue, the 1.9.4 distribution works perfect,

    Many thanks to Srdjan Boskovic for the support
