Hi
steps:
0)Append structures allow you to attach fields to a table without actually having to modify the table itself. You can use the fields in append structures in ABAP programs just as you would any other field in the table.
1)Click on the append structure tab and opt to create new
structure.
Append structures allow you to enhance tables by adding fields to them that are not part of the standard. With append structures; customers can add their own fields to any table or structure they want.
Append structures are created for use with a specific table. However, a table can have multiple append structures assigned to it
2)Customers can add their own fields to any table or structure they want.
The customer creates append structures in the customer namespace. The append structure is thus protected against overwriting during an upgrade. The fields in the append structure should also reside in the customer namespace, that is the field names should begin with ZZ or YY. This prevents name conflicts with fields inserted in the table by SAP
