Re: How to pass arguments to CREATE_STREAM via Slug parameters ?

You can use the component sap.ui.unified.FileUploaderParameter to pass a slug.

But you have only one slug per Upload. So, you need to concatenate your data using some separator defined by yourself.

In the example below I used a pipe character, "I", as separator:

oHeaderParameter = new sap.ui.unified.FileUploaderParameter({  name : "slug",  value : "argument1|argument2|argument3"
});
oFileUploader.addHeaderParameter(oHeaderParameter);

Now, you just need to make your own logic to extract and split the SLUG in many values on SAP Gateway.

Hope it solve your problem.
