How To Fix RSCRT340 - RDA daemon not started; completed delta requests not in target

RSCRT340 - Overview

• Message type: E = Error

• Message class: RSCRT - Near-To-Real-Time Messages

• Message number: 340

• Message text: RDA daemon not started; completed delta requests not in target

What causes this issue?

You tried to start a daemon for real-time data acquisition (RDA) to
which the data transfer process &V1& is assigned. The PSA table of the
source of this DTP contains completed delta requests that were not yet
updated in the target of this DTP (InfoProvider &V2&). One of these
requests has the SID &V3&.

System Response

The RDA daemon cannot be started before all the completed delta requests
from the corresponding DataSource have been updated in the InfoProvider
&V2& and the data has been activated there, if necessary.

How to fix this error?

If you still want to supply the InfoProvider &V2& with data by RDA, load
the missing delta requests from the PSA and activate the data in the
InfoProvider if necessary. You can change the type of the data transfer
process &V1& to <ZK>Standard </>and execute the DTP. If required,
activate the corresponding requests in the administration view of the
InfoProvider.
If you do not want to define further parameters for the InfoProvider
&V2& by RDA, delete the assignment to the DataSource in the context menu
of the DTP.
Then start the RDA daemon again.
