Adding new customized field to "Delivery Schedule" tab item detail in Me22N

Hello All,

1. I have to add new customized field to "Delivery Schedule" TAB item detail in Me22N.

2. I see that there is MEPO1320 structure, that I have to add here this new field.

I suppose that in addition I have to add this new field to table EKET to save his vakue in data base.

Please, advice, how I can do it.

Or, may be, there is another way to do it, without adding new field to MEPO1320 ?

Thanks a lot,

Daniel.
