Do you mean attaching an EXCEL file to a Work Object or uploading in Designer Studio (for instance for Data Pages etc ?)

I try to explain.

I added a button on my section for uploading the excel file by calling the activity "MSOParseExcelFile" in my activity.

After uploading I view the data in my clipboard regularly, but the application does not return in the section containing the key with which I uploaded.

Thanks for the support.

There are probably better suggestsions available for this: but as a high-level approach :

Try creating a 'wrapper' Activity and then marking this as a 'Utility'; if you put this Utility Shape into your flow; you can perhaps use OOTB buttons to avoid having to make calls from your UI. (MSOParseExcelFile - I guess doesn't know how to re-direct you back to your screen).

(BTW: how are you uploading the file to PRPC in the first place - you writing it to the 'StaticContent' directory etc or something ?)

Hi..

Try checking the functionality involved in attach a file functionality ! May be you can use similar kind of control.

Others option could be to use a modal dialog for the same functionality .
