I crated a table and use your data:

CREATE TABLE Fehlermeldung (
    Field01 VARCHAR(32000),
    Field02 VARCHAR(32000),
    Field03 VARCHAR(32000),
    Field04 VARCHAR(32000),
    Field05 VARCHAR(32000),
    Field06 VARCHAR(32000),
    Field07 VARCHAR(32000),
    Field08 VARCHAR(32000),
    Field09 VARCHAR(32000),
    Field10 VARCHAR(32000),
    Field11 VARCHAR(32000),
    Field12 VARCHAR(32000)
)

Use the data you provided:

INSERT INTO "Fehlermeldung" VALUES (
1001021,
'qsDataFieldOutOfRange',
'10',
'Der Wert ''<wert>'' des Datenfeldes <feldName> \"<feldBezeichnung>\" ist <artDerAbweichung> als <feldBound>.',
'<params wert=\"\" feldName=\"Modul.name:Bogen.name:Feld.name\" feldBezeichnung=\"Feld.bezeichnung\"  artDerAbweichung=\"Ein Wert aus [größer, kleiner]\" feldBound=\"Minimal- oder Maximalwert des Feldes je nach Wert in artDerAbweichung\" />',
'',
'Leistungserbringer',
'',
'',
'Leistungserbringer',
'Als Template-Meldung kann diese auch auf modifizierte Daten der DAS zutreffen.',
'')

And the write is ok.

The class structure created:

 

/// 
Class User.Fehlermeldung Extends %Persistent [ ClassType = persistent, DdlAllowed, Final, Owner = {desenv}, ProcedureBlock, SqlRowIdPrivate, SqlTableName = Fehlermeldung ]
{

Property Field01 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 2 ];
Property Field02 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 3 ];
Property Field03 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 4 ];
Property Field04 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 5 ];
Property Field05 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 6 ];
Property Field06 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 7 ];
Property Field07 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 8 ];
Property Field08 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 9 ];
Property Field09 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 10 ];
Property Field10 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 11 ];
Property Field11 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 12 ];
Property Field12 As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 13 ];

/// Bitmap Extent Index auto-generated by DDL CREATE TABLE statement.  Do not edit the SqlName of this index.
Index DDLBEIndex [ Extent, SqlName = "%%DDLBEIndex", Type = bitmap ];

}

Check the definition of the fifth property if there any unusual restriction.
Or, if you could, post the class definition here.
 

Hello

Older professionals can confirm it, but this operation ordering premise is older than the InterSystems product. It comes from the origin of MUMPS. So I don't think it's something InterSystems can or should change.

When I discovered this feature of language, I decided that all my codes involving numerical calculations should always be formatted with "(", determining precedence, even if precedence is natural to language. And I do it that way regardless of language.

For example, in COS this calculation would be natural:

Write !,10 + 10 * 10
USER> 200

But I would always code like this:

Write !,( 10 + 10 ) * 10
USER> 200

This way the code will be readable even for "Non MUMPS" coders, and this piece of code could even be migrated to other languages without problems.
