Holding data in Screen in me21n at item level-- enhancement MM06E005

Hi Frnds,

Need a help from your side,

Actually i added one custom tab in me21n screen

using enhancement MM06E005

and then i added one field in that tab , that field is also customesd (CI_EKPO-field_name)

Actually the problem is when i m creating PO of more then one item and putting the value of that

like po 1234

item 10 its field_name value x

item 20 its field_name value y

so screen is always showing the last value but in table both the values get save.

Suggest me what can i do to resolve this.

Regards

Yogesh
