How To Fix SY287 - This flush is unnecessary because it transports a queue w/o return value.

SAP Error Message - Details

• Message type: E = Error

• Message class: SY - ABAP/4 system messages

• Message number: 287

• Message text: This flush is unnecessary because it transports a queue w/o return value.

What causes this issue?

You should only flush an automation queue when you definitely need
return values from a CALL METHOD or GET PROPERTY. Flushing a queue that
does not contain any return values is expensive in terms of runtime and
is poor programming style. The system flushes automatically at the end
of the PBO event, so there is no danger that automation calls will not
reach the frontend because a flush is missing. If short dumps occur
when you omit the flush, use the Frontend Automation Trace to find the
error.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
