Screen output without connection to user. 

this is because , the underlying ABAP code is trying the call a screen which is not possible in RFC calls.

Hi Raja,

but it works when i code inside R3 system use

CALL FUNCTION 'a'

STARTING NEW TASK '1'

DESTINATION 'b'

Performing Resp ON END OF TASK.

i just want to call my fuction 'a' by JCO... because i need complie it to a EXE file wich can be executed when windows start.

Many thanks !

but it works when i code inside R3 system use 

thats because you are in sapgui environment which can process sapgui screens.

what does the function 'a' exactly does? may be we can think of an alternate.

Hi Raja,

the fuction is going to execute catt/ecatt which nees SAPGUI sometimes...

Many thanks anyway for your help!
