Field value in POWL standard column

Hi All,

I am on SRM 7.0, ECC 6.0, Classic scenario.

I have added standard field BE_OBJECT_ID to populate backend purchase order number in Employee Self Services POWL by adding the field to the relevant feeder type.
However, after PO is created in backend, the purchase order number is not getting populated in the POWL column.

Am I missing out something here ?

Appreciate your assistance & inputs.

BR,

PD.
