How To Fix RSQU019 - Data still in delta queue - no init possible

RSQU019 - Overview

• Message type: E = Error

• Message class: RSQU - S-API after 4.0: Delta Queue, Real Time Update

• Message number: 019

• Message text: Data still in delta queue - no init possible

What causes this issue?

A delta update already exists for this DataSource in the OLTP system.
There are currently data records for this update in the delta queue
that either still need to be picked up or are being reserved for a
repeat of the last delta request.

System Response

It is therefore not possible, at the moment, to use enhanced selection
parameters to initialize the update.
This could lead to inconsistencies: A record might arrive in BW, and be
in the delta queue, through the init. request that caused the error.
It would then arrive as a duplicated data record in BW , with the
next delta request.

How to fix this error?

First, load all the data records in the delta queue, per delta request,
into BW, and intitialize again.
If this is not possible because there has not been a successful
initialization, delete the data in the delta queue with the report
<ZH>RSU20001</>.

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