Message text: Customizing changes detected at target ledger &1, setting: "&2"
The current customizing settings of the target ledgers assigned to the
project have been compared with the settings of the customizing snapshot
that was taken at the time when preparations were completed. The system
shows any detected differences at target ledgers when data transfer
shall be confirmed. In this case a difference was detected for target
ledger &V1& at setting: "&V2&" (&V3&). Technical fieldname in the ledger
table is  "&V4&".
In general, this kind of subsequent customizing changes are not allowed
and cannot be handled properly during data processing, i.e. the current
data of target ledger &V1& might be inconsistent.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
In non-productive systems you can either reset the data in the cockpit
first and reset "Complete Preparations" afterwards to update the
customizing snapshot when "Complete Preparations" is performed next
time, or you can change the message type (and even suppress the message)
in transaction <DS:TRAN.OBA5>Change Message Control</> using the
application area FINS_FI_SIF. If the message type is I (Info), S
(Success) or W (Warning), the data transfer can then be confirmed.
Note: This function is only supported in non-productive systems.
Intermediate Customizing changes will always cause an error message in
productive systems and a confirmation of the data transfer will no
longer be possible.
