Field name DUMMY is reserved (Do not use structure as include in DB table)
We are trying to add a custom field, e.g., called ZZZ in structure MCEKKO (Purchasing Document Header) by creating a new custom append structure and add the field ZZZ into it, then activate the new append structure, but get warning msg like "Field name DUMMY is reserved (Do not use structure as include in DB table)".
We do find a field called DUMMY in the structure MCEKKO. How to get rid of the warning msg and successfully activate the new custom append structure with the new field ZZZ?
We will give you reward points for correct solutions for the above problem!

You can name fields DUMMY.
Some field names are reserved.
They cannot be used.
But since it is a warning you can ignore that.
Else <b>rename the field as DUMMY1.</b>
Similarly you cannot name your field in your database table as <b>FORMAT</b>.
