SUS Custom field not visible in SUS PO

Hi Experts,

As per SAP note 762984, we have enhanced the structures such as :

Purchase order           | Header |       INCL_EEW_PD_HEADER_CSF_SUSPO

Order confirmation      | Header |      INCL_EEW_PD_HEADER_CSF_SUSPCO

In Config I have created fields as per the notes

Table                          colunm         Possition          Field Name               UI type

Z.PO.DET.EDIT     1               1                    ZZSUSPOF1     INPUT

Z.PO.DET.VIEW     1               1                  ZZSUSPOF1     INPUT

as I'm able to see the input field in display mode but not in process mode( Edit mode )

Kindly Help me on this.

Best Regards
