Hello Community

I want to generate a pdf in node red and want to enter the file name (and maybe the location) with variables. I heard that this could work with the msg.filename, but I couldn't find anything. can someone help me?

So I can generate a pdf but the file name is fixed.  
Thanks for your help!

Mauri

remove the hard coded filename from the file node & in your function add something like...

```auto
// your code
const reportDate = new Date().toISOString().replace(/[TG]/g,'_').replace(/:/g,'-').substring(0,19);
const reportName = 'mydata'
msg.filename = `c/reports/report-${reportName}-${reportDate}.pdf`
return msg;

```

How can i program if there is no data the line should not be written?

For example this line:

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/b/0bb4a094fc3ce7af12f65c57bbc7def9d37a9a55.png)  
If there is no data from "0x\_0x\_we\_id", then the column should not be written...

If you post code/flow instead of pictures I can show you.

PS...

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```

````

See this post for more details - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

PS2  
If you dont reply to my comment I have no idea you have replied (there are 2 reply buttons, 1 at the bottom and one on a users last comment - this one notifies the user you are replying to them)

The flow is in a -txt file, 'cause it's to big to share with the ```

I hope you can understand it...
