Posted on by Zaid Khan 17
Hi Friends,
 
I created Vendor then created the purchase order but when I add purchase order line an error came
"Common Language Runtime detected an invalid program."
and it won't allow me to save the purchase order line.
 
Please help me to resolve this issue.
 
I don't understand why it stops there. What could be causing the error?
I have the same question (0)

    Hi Zaid,
     
    You can try to update a test environment to version 10.0.40 (PU64) which is the current version and see if this solves the issue.  
    What exactly do you mean by "ISV runtime is running"?
    In what area do you have customizations?

    Hi André Arnaud de Calavon,
     
    D365FO (Platform update60) 7.0.7036.51 and have some customizations 
    Also ISV solution is not installed but ISV runtime is running 
    And I am using Microsoft edge browser
     
    But still facing same error "Common Language Runtime detected an invalid program."

    Also it says "Some of the information that you entered is not valid. You must enter valid information before you can continue."
    When I hit save.
     
    Thanks.
    Zaid.

    Hi Zaid,
     
    In my environments, it is working correctly. 
    Which exact version of Dynamics 365 Finance are you using? Do you have customizations or ISV solutions installed in your environment? Did it work before? If so, was there any change to the environment? Which browser are you using?
