SAPWR system specification problem;  We are implementing SAPWR for our guixt scripts. When we try to specify a system ( i.e. SAPWR, dest=D51:z.guixt ) we get an SAPWR RFC error popup. The popup message is:
open 'saprfc.ini' failed : no such file on directory. What is the explanation and the solution, please?

Here we are using the SAP standard for RFC connections.  The destination must be described in a local file "saprfc.ini". A typical entry there looks as follows:

DEST=TST
TYPE=A
ASHOST=pw112.xt1.com
SYSNR=12

Please see the SAP RFC documentation for details; an internet link to SAP RFC documentation is:

The file saprfc.ini is either in the sapgui working directory "...\SAPworkdir", or you use the environment RFC_INI to name the saprfc.ini file.
