I have a custom entity named "ADS" in CRM 4.0 environment. I have created a custom button in phone call and once clicked it directs to ".aspx" page, I am able to receive the phonecall id from phonecall from aspx page. but when i redirect to "ADS" form (http://CRMSERVER:5555/CRMTest/userdefined/edit.aspx?_CreateFromType=2&_CreateFromId=
+ p + "&etc=10001# - this url redirects to ADS create form, where the user enters the detail) from the .aspx file. I lose the details of phone call id. There is a ADS lookup in phonecall created by N:1 relatiohnship with ADS and phonecall. I need to map this back to the new ADS that is being created, which means the ADS lookup in phone call (new call) should be mapped with the new ADS created, once the ADS form is saved.
I would like to know how can I map the new ADS (lookup in phonecall - thats being created newly) to the phonecall . Please let me know asap
