I have encounters this abap snippet that I have difficulty to comprehend.
call function 'com_invoke'
destination pv_wrkdest
exporting
%instid = pv_instance
%method = 'FieldCountGet'
importing
%return = lc_return
fieldcount = pv_fieldcount
exceptions
communication_failure = 1
system_failure = 2
invalid_instance_id = 3
others = 4.
What does the percent sign indicates in the %instid, %method and %return parameters?
Thanks.
