I’ve worked with SAP guys before, and I would be shocked if SAP could not, or would not be able to recognize quotes and what they mean, and how to process it.
Tabs and commas are internationally recognized field delimiters and quotes are internationally recognized text identifiers.
There is zero doubt in my mind that the SAP developers are aware of this.
Anyway, I don't know what the bleep happened yesterday, or how it actually happened, but yesterday, I know I saved the file as MS-DOS text and there were no quotes.
Today, I am unable to reproduce that.
Fortunately, I know I did not hallucinate it because I actually do have the file to prove it.
How it happened, I apparently cannot say.
Here is a work around that I know works (because I’ve checked it several times).
Copy your finished data in Excel and paste it into Word.
In Word, select all the data and convert the table to text.
A dialog box will ask you to select a delimiter, select TAB.
Then save the file as plain text.
You will not have any quotes.
