How to extend Infosystem Detailled list?

[Former Member]

Dear experts,

I tried to extend the drop down menu for the list type in the transaction COOIS with a customer entry.

I used the transaction COISL to copy the entry with key

10 production order - PPIOH000 – 3 – IOHEADER - IOHEADER_TAB - CL_COIS_DISP_LIST

To a new one:

10 production order - ZPIOH000 – 3 – IOHEADER - IOHEADER_TAB - CL_COIS_ADD_LIST

I tried to use the class CL_COIS_DISP_LIST instead of CL_COIS_ADD_LIST but the entry does not appear in the drop down menu in TA COOIS.

There is also a BAdi implementation for WORKORDER_INFOSYSTEM, but there is no possibility to enhance the drop down menu.

What I need to do to see and use this customer entry?

Thank you for your help!

Regards,

Matthias Keck
