Unused fields in PO items tabs - EKPO

Hi all,

We are planning to use following fields from table EKPO (PO ITEM) for passing some information as I found these fields are not used currently..

A) Date field

1) DRDAT - Last transmission

2) NLABD - Next forecasting delivbery schedule transmission

3) NFABD - Next JIT delivry schedule

B) Character field (20)

1) GRANT_NBR - Grant

My problem is that I am not able to see the above fields in Purchase orders, even though they are in table EKPO.

Can some one guide me in this matter.

Thanks,

Vengal Rao.
