BDC Page down issue in PA30

Hi all,

I am using BDC for PA30, for uploading Exemptions infotype 0582. I am trying with ok code '=P+', P++, PNPG, KEIN, NP, POPO, POAN, PEND, POPO_T, PAUA_T, etc.

But i could not achieve Page down option. The table control is partially filled.

When i use BDC for 585 infotype, I could achieve Page down using P+ where all the 30 records of the table control is filled.
