Add a specific text and variable
The trick here is to change the content of command \location to
\setkomavar{location}{%
\\[\baselineskip] \\[\baselineskip]
\flushright\small Rechnungsnummer: \invoiceReference\\[1pt]
Kundennummer: \customerNumber
}
I added the line Kundennummer: \customerNumber which means you have to add a new command \customerNumber to the datas for your customer(s). It is better to use a command that writing it each time you write an invoice new. It gives you less errors.
But now you have to define this command like:
\newcommand{\customerNumber}{1234567} % Kundennummer
Best solution would be to define two new commands like
\def\invoicenr{Rechnungsnummer:}%
\def\customernr{Kundennummer:}%
to make your invoice more language independent (off course you need then to define this words for the other languages too). Then you can use
\setkomavar{location}{%
\\[\baselineskip] \\[\baselineskip]
\flushright\small \invoicenr \invoiceReference\\[1pt]
\customernr \customerNumber
}
To avoid the splitting of Rechnungsnummer: and current number you can use shorter Names like
\def\invoicenr{Rechnungsnr.:}%
\def\customernr{Kundennr.:}%
With the complete code (based on your last question with the described changings above)

you get the result:
If you want Kundennummer and rechnungsnummer and the relevant numbers to be one below the other simply change \location to
\setkomavar{location}{%
\\[\baselineskip] \\[\baselineskip]
\flushright\small \invoicenr\\[1pt] \invoiceReference\\[1pt] % <=========
\customernr\\[1pt] \customerNumber
}
with the result:
Please see that you can use
\newcommand{\invoiceReference}{2019\_01\_14\_01}
to generate an invoice reference number 2019_01_14_01 but I would not recommend that. Better use 2019-01-14-01 ...
You could just use a tabular environment with two lines for the reference:
