Structure of SAP Master Tables

[Former Member]

Hi All,

Could anyone of you indicate what are the advantages and disadvantages of modifying the structure of SAP Master Tables. Is this recommend it?

Is there any white paper or document explain it?

Any help you can provide it is greatly appreciated.

Thanks

Edgardo

do not change master tables, use append structures or create "Z" tables

Hello Edgardo,

Now you have the answer for this.

Suppose we change the structure of a master table like we add a new field for example . How all the reports,scriptts, forms,module pools etc etc take care of this?

Are we going to modify each and every reports,forms etc?

Of course it is possible to modify any table, if not from sap then from SQL but how to take care of the relationships which it bears with other objects?
