Answer / santhosh dasari

a.Normal Structures (which are includes) starts with .include where as Append structures starts with .append
b.Append Structures are used only to enhance standard tables where as Includes are used to enhance Ztables.
c.Append structures should be added at the end of a standard table. This is a must because we should not change the original standard table in the middle whereas Include structure allows adding one or more structure into structure or table. Also placed positioning anywhere. Up to 9 include structure can be used in a table.
d.Note: Some standard tables for which there are long data type fields cannot be enhanced because, long type fields should always be at the end and append structures should also be at the end, so there will be a conflict.
