Add Prortfolio Item Custom Fileds

Dear Expert,

I have requirement to add the certain custom fields in Portfolio Item.

I have added fields in structure /RPM/TS_ITEM_D_DATA_CUST in customer include CI_RPM_ITEM_ATT and am able to add this custom fields with drop down on front end by config and this works fine.

Now i want to have dropdown with multiple selection for some fields. I was thinking to enhance the standard webdynpro component - /RPM/ITEM_DETAILS view - VI_GEN_INFO.

However am not able to see the custom fields added in CI_RPM_ITEM_ATT in to context node ITEM_ATTRIBUTES.

Need your assistance to achieve this? May be in different way using BADI or enhancement.

Regards,

Youraj Thete
