Bug #6960 for SAP-Rfc: SAP::Iface returns confusing values

Subject:

SAP::Iface returns confusing values

Hello, I was writing a test script which should connect to a SAP system, call the function "TF_FSYS_SINGLE" and print out the path and the sizes of different directories on the file system (it's a SAP standard function). Therefore I used Perl 5.8.3 built for i586-linux-thread-multi and the SAP-Rfc package 1.32. The R/3 Release is 4.6C. The output in the SAP system is OK, but on my linux machine I got wrong directory sizes (often neg. or very big integers). Maybe it's my fault... I'm not sure, but I hope you could help me. Thank you very much. With kind regards, Osman Redzepi The test script: #!/usr/bin/perl use strict; use SAP::Rfc; my $rfc = new SAP::Rfc ( ASHOST => 'e...', USER => 'Z...', PASSWD => 'k...', LANG => 'DE', CLIENT => '900', SYSNR => '09', TRACE => '1' ); my $iface = $rfc->discover("GET_FSYS_SINGLE"); if (defined $iface) { $rfc->callrfc($iface); foreach my $row ( $iface->tab('TF_FSYS_SINGLE')->hashRows() ) { my $fsn = $row->{'FSYSNAME'}; my $cap = $row->{'CAPACITY'}; my $fre = $row->{'FREE'}; print "> $fsn | $cap | $fre < \n"; } } else { print "Error: " . $rfc->error() . "\n"; } $rfc->close(); This is the output, how it looks like on my console: Show quoted text

Hi Osman, There are long standing issues that I have had with Endian-ism of systems that SAP::Rfc works with/on. This is mainly due to the fact that I have never had access to all the flavours of UNIX that SAP runs on in order to test and work through the problems. Your client side is running on Linux, but what are the details of the SAP R/3 server? Perhaps you could set TRACE => 1 in the $rfc = new SAP::Rfc() and provide me with the *.trc files so that I can see what your setup is? Cheers, Piers Harding.

Hello Piers, thank you very much for the fast reply... I will provide you with the necessery information. Well this SAP instance runs on a HP 9000/Rp 4440 (RISC technology). The OS version is HP-UX B.11.11 U 9000/800. I wrote a short test program in C which tells me that's a BIG ENDIAN machine! A copy of the trace file is attached too. I had to overwrite some entries (DNS-Entry, IP-Adresses, User name) 'cause I don't want to get in trouble with my boss... ;) Thanks and bye, Osman [PIERS - Thu Jul 15 02:55:50 2004]: Show quoted text

Hi Osman, I have created a release candidate for this problem, but I will not be able to test if completely for a few days. If you are in a hurry, you can test the attached. Cheers, Piers Harding. On Thu, Jul 15, 2004 at 06:28:52AM -0400, Guest via RT wrote: Show quoted text
