You use the field-transport macro to send all data accumulated by field-set calls to the ITS during PBO. The data is sent synchronously.
Syntax in the Standalone ITS
With the standalone ITS, this is automatically performed by the flow logic runtime.
Syntax in the Integrated ITS
In ABAP in the integrated ITS, the syntax could be as follows:
loop at my_list into wa. field-set 'MY_LIST-AIRLINEID' counter wa-AIRLINEID. field-set 'MY _LIST-FLIGHTDATE' counter wa-FLIGHTDATE. field-set 'MY _LIST-CITYFROM' counter wa-CITYFROM. field-set 'MY _LIST-CITYTO' counter wa-CITYTO. add 1 to counter. endloop. field-transport.
