Issue with Reference table/ALV

Hi All,

I am facing a weird issue in Table -> ALV.

In ALV I am using VNAME: Joint Venture, Table: T8JV..., EGRUP: Equity Group, table: T8JF.

For both the table, I am passing a dummy values for Joint Venture and Equity group. But in ALV, when I pass the Joint Venture as 100000 and Equity group as L01 (these values I am passing to the table.) When i click on F4 of Equity group field, I am getting error as
NO INPUT HELP IS AVAILABLE.

Please check the screenshot.

Let me know where I am missing.

Regards,

Kiran
