Call Function - Dest "RFC"

[Former Member]

Hello,

i have a big problem.

I´ve written a web dynpro programm.

In this program i call a function:

CALL FUNCTION 'READ_DAT' DEST 'Z_READ_DAT".

Z_READ_DAT is a RCF which points on a exe file on my pc.

When is use this Function in SAPGUI all works fine, but when i call it in WDA there is a dump.

"Cannot open RFC". ST22 says EXEC_SAPGUI : cannot open sapgui.

What can i do?

Hi Benjamin Pfahl ,

there are cetain RFCs that cannot be used with Webdynpro, like gui_upload and all. the Fm 'READ_DAT' DEST 'Z_READ_DAT, since its working fine in normal abap means it cannot be used with wda, the Fm might be using sap gui to fetch from your pc.

Hi,

thank you for your answer.

You are right.. this RFC tries to communicate via GUI.

We´ll try another way.
