The new version of the SAP standard table is activated and the new field is appended to the database table.Please note the following points about append structures:
No append structures may be created for pooled and cluster tables.If a long field (data type LCHR or LRAW) occurs in a table, it cannot be extended with append structures. This is because such long fields must always be in the last position of the field list, i.e. they must be the last field of the table.
If you as a customer add an append structure to an SAP table, the fields in this append structure should be in the customer namespace for fields, that is they should begin with YY or ZZ. This prevents name collisions with new fields inserted in the standard table by SAP.
If you as a partner have your own reserved namespace for your developments, the fields you select in append structures should always lie in this namespace.
