Hi Ernesto,
sorry by my confusion, maybe it is due a language translation. My original request was to submit a form to a Sharepoint list with an attachment Read Only. Using SubmitToSharePointList I am able to do, but the attachment is R/W. I made a mistake, assuming I had the same process than using SaveToSharePoint and doing the replacemet of File by Http in @qRuleLink field that changes Read Only by a R/W option.
Now I figure out that this is not related to qRules, but Sharepoint user's permissions, and knowing that I configured a security group with Add Item and Exclude Item, and unchecked Edit Item to the Sales people and I notice that all time I was trying to execute SubmitToSharePointList, the user was being prompt to inform his credentials. At this point does not matter how many times I inform the correct Login/Psw, I never have the attchment sumbitted.
Any idea how to solve this problem ?
