Set Editable for the entire column in WD Table/ALV

Hello Gurus,

I am developing a WD Application with Table/ALV option. In my Table/ALV, I have Material, Material Description and Quantity fields.

My requirement is to display the Table/ALV with Material field as a Editable field for all the rows. Here user will manually enter the Material Number and logic will populate the Material Description and Quantities base on some action.

Somehow, I am unable to set the MATNR column as a editable column for all the rows (Make Material field as a editable field for empty lines as well).

Can anyone please help me out with this requirement.

Point will be rewarded.

Thanks in advance.

Thanks

Shyam
