data diffrent in EKPO and ME23n

Hi,

I am looking at PO's in EKPO table and also looking at ME23n transaction.

The P.R's(BANFN) field value is present in ME23n transaction, but is not shown in EKPO table.

As ABAP'ers would be looking into data present in the tables, the data looks to be different from that of actual data.

Any ideas how to check where the problem lies.

Thanks

Sachin
