Problem when call transaction MD04

[former_member1344871]

Dear All

       I come across a problem

      We need a report which is similar to MD4C

      So I use alv form to create a report  and refer to this blog http://blog.csdn.net/zcy691640/article/details/44078171

    

      Use FM: MD_PROJECT_REPORT.

    

    The problem is  when I  Call transaction MD04 in  alv  and double click on one item.

     The program crashed.

  

  

  The error message displays as below

But when I use Leave to transaction 'MD04', I works.

I tried to debug and found that before the alv result displayed ,the value of  I_NODE_KEY is "1",but after I double clicked on one item to try call

'MD04',the value of I_NODE_KEY is null.

Maybe I need free Memory or internal sessions before  use "Call transaction 'MD04'",or set export "1" to I_NODE_KEY?

Could anybody help to slove this problem?

Thank you very much.
