Hello,
Is it possible to enhance an existing LIS structure? The LIS is currently being used to store the weekly bucket (planned independent demand) and now the ask is to add one more key field to an existing LIS. Is it possible or shall I go ahead with a completely new structure?
Is it also possible to transfer the data from an existing LIS to a new one if the new one holds one additional field?
Thanks,
Kumarnae
Hello kumarnae
Although an info structure is technically implemented as a transparent database table, you should never try enhancing it as other tables with append structures. The info structures are defined with the MC21, MC22, MC23 transactions. An info structure is composed of characteristics and key figures:When an info structure is activated, the corresponding database table is created. The characteristics become the key fields of the table.
If you need to add a new key field (characteristic) to your info structure, you can either add a new characteristic to an existing info structure and create a new one. Bear in mind that when you add a characteristic and reactive the info structure, its content will be wiped out. Also the number of characteristics in an info structure is restricted to 9 - see the note 38891 - Restriction of number of characteristics for explanation and workaround.
If you decide to create a new info structure, you can copy the content of the old one with the MCSZ transaction. See the documentation to IMG node: Logistics - General -> Logistics Information System (LIS) -> Data Basis -> Tools -> Copy Management for details.
So the decision to either change an existing info structure or build a new one, really depends on your specific business scenario.
