Adding Additional Parameters (SLUG) to sap.m.uploadCollection

Question

Dear All,
Kindly help to find out a way to add additional request parameters (SLUG) while uploading a file from UI5 front end through gateway using Sap.M.UploadCollection control before uploading the file.
insertCollectionParameter is working but i would like to add dynamic parameters before the POST request is fired.
Kindly help accordingly.
Thanks,

Hi,
slug is one of the header parameters, if you want to add multiple values i suggest you use a separator, e.g. "|" so you can easily split the parameters in the backend.
e.g.
var oHeaders = {
                    "x-csrf-token" : header_xcsrf_token,
                    "slug" : sap.ui.getCore().byId('masterSelect')
                            .getSelectedKey()
                            + "|"
                            + file.name
                            + "|"
                            + file.type
                            + "|"
                            + sap.ui.getCore().byId('bestandsNaam').getValue()
                            + "|"
                            + sap.ui.getCore().byId('typeSelect')
                                    .getSelectedItem().getId(),
if you want something dynamic, you could use a javascript array:
var slug = slugArray.join("|");
in backend:
CONSTANTS:
  gc_delimiter(1)    TYPE c  VALUE '|'.
SPLIT iv_slug AT gc_delimiter into itab_slug.
Kind regards,
