Hi Dan

This sounds like this context information is getting confused.  Have a look at the messages in the system and SQL log for clues but also look at the URL that is used to call the page when the error takes place vs when you can click the button again. 

Hi, 

Here are the URL's for when I select the page either first or via the person page and the second one is when I click on the data delivery tab again. 

CustomPages/DataDelivery.asp?SID=9641218026423&Key0=1&Key1=948&Key2=5997&J=DataDelivery.asp&T=Company

CustomPages/DataDelivery.asp?SID=9641218026423&Key0=1&Key1=948&Key2=5997&J=DataDelivery.asp&F=DataDelivery.asp&T=Company

• J is the target page for the URL
• F is the original context (or page)
• E is the target Entity
• T is the default tabgroup

The original link is missing the F reference.  Try adding that into the URL and see whether the error still takes place. 

Hi,

when I go directly to data delivery from summary(company) there is no F reference it only appears if I click on data delivery again or move from another custom entity.

We only get the error if we have searched for the company first and clicked on people before moving to a custom entity. I have checked the asp and there is CRM.GetContextInfo("Company","Comp_CompanyId")
