Experiencing issues with t-code ME23N

Hi Gurus ,

could anybody guide with the following issue:-

ME23N/ME23 in ECC 6.0 system doesnot show up the column :Amount in Local curency at the itemlevel details of a Purchase Order. There has been a recent upgrade in the system and after that when we compare we see that.

SAP4.7 shows up the column 'Amount in Local Curr' at Item Level for any Purchase Order.But the same thingh when checked up with any PO in ECC 6.0 system it doesnot appear.

Could anybody please guide as per how shall we check the Screen fields assigned to ME23N t-code in SApsystem ECC6.0.

Thanks

Trina
