Logon currency &1 is different from currency in existing data records. &2

What causes this issue?

You attempted to start the data selection in update run with the
restriction that not all data records from the respective worklist for
the official declaration should be deleted.
The currency units of the data records that are not to be deleted were
checked for the fields <LS>Invoice value</> and <LS>Statistical
value</>. The system found that the declaration currency of the data
selection differs from the currency of the data records that are not to
be deleted.
Please note that the official declaration may only be created in one
currency. For this reason, the data selection is cancelled. For
example, data records are found in currency <ZH>&V3&</>, but the
declaration currency you entered is <zh>&V1&</>.
Another cause for varying currencies can be accounted for in special
incidents. The following are restricted to intra-European Union trade
statistics (INTRASTAT), however.

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

Inbound transport from internal allocation (SD)
Goods dispatch from returns and credit memos (MM)
Generally, each data selection deletes only the data records from the
corresponding worklist that were created by it. If the usual data
selection and the data selection for special incidents are started with
differing declaration currencies, this message also appears.

System Response

The system cancels the edit process.

How to fix this error?

Decide which currency the official declaration should be created in.
If the declaration is to be output in declaration currency <ZH>&V1&</>,
start the data selection in update run with a blank parameter entry for
<LS>Deletion type</> ('_'). Please note that this action causes all
data records that were created or changed manually to be deleted.
If you want to create the declaration in currency <ZH>&V3&</>, you can
restart the data selection after changing the declaration currency to
<ZH>&V3&</> but otherwise leaving the parameters unchanged.
If you are working with special incidents, make sure that the usual
data selection and the data selection for special incidents contain the
same declaration currency.
