Adding custom fields to vl02n / vl03n screen at item level.

I want to add 5 custom fields to the outbound delivery screens (vl02n and vl03n) at the item level.

I have already implemented the BADI : LE_SHP_TAB_CUST_ITEM

In the method: ACTIVATE_TAB_PAGE, I have written the following code:

ef_caption = text-000. " Screen Caption

ef_program = 'SAPLZSD_STUFF'. "SAPL Followed by the Function group created ZSD537_HEAD (created)

• ef_position = 7. " Tab Position

ef_dynpro = '9000'. " Screen Number

• cs_v50agl_cust = 'X'.

But custom Tab is not added to vl02n or vl03n at the item level.

I tried adding a custom tab to the header of these transactions in exactly the same way( I used the same function group and the same screen as I used for addition of data to item level), and it worked. But addition to item level does not work.

Any help please??
