How can I open a PDF stored in IXOS and then display it in a BSP

Question

Hello gurus,
I have created a PDF icon and an onclick action to open a pdf, that displays on every row of an assignment block in the actions column, but I do not know the technical process to determine how to get a PDF from the IXOS system from the line selected. (even if I know it depends on an ID attribute of that assignment block) I want to to call a transaction launcher with the url for the pdf in the IXOS that has an ID that identifies which line in the assignment block the user has clicked the pdf icon for (does that make sense?)
Therefore, I am assuming the PDF should correspond to the relance ID of the row in the assignment block, but I would like more information as per the business logic involved in able to achieve the desired results for this particular specification. I already confirmed that the XURL or any other attribute in the BOL object does not contain the URL to use for this. I have looked at the class I was told that it may contain the required business logic for determining which PDF in IXOS to fetch for a particular row, and I am currently trying to reverse engineer the logic through looking at other code and using the debugger, but so far I haven'T had much luck.
Here are some questions I have now for the functional side in the meantime:
1) Can we fetch the PDF in IXOS for each line of an assignment block?
2) Which URL should I call with the transaction launcher? a URL link to the PDF on the IXOS system??
3) Do we have to configure a transaction in the IMG to be launched?
4) Do we have to create a logical link there that I will make dynamic to call the right PDF for each table line? 
5) Are there any existing examples of this or a similar functionality/ logic that I could refer to, preferably in CRM 7 WebUI?
6) Do you have any code to just display a PDF in a new window? Or prompt a download?
One possible way I thought of would be for me to have a logical link defined in the IMG, that I could call passing it different attributes (eg. some object id, etc) and then return the PDF and display it in the UI in a new browser window by itself. Alternatively, we can just prompt a download. What do you think would be the optimal behaviour here?
Please do not hesitate to propose any potential solution. Any partial answers/ links to wikis/ other threads, anything would be much appreciated.
Thank you in advance.
Best regards,

Hi,
I partially answered your question in another posting but I feel that you´re in the wrong forum for your problem. This is for BSP development and you talk about CRM.
