Functionality
The BAPI BAPI_NETWORK_COMP_CHANGE changes existing material componentsin the network (NUMBER). Therefore it is possible to change multiplenetwork components belonging to the network object by calling one singletime.
The BAPI can be called repeatedly, until a LUW is completed with theBAPI Commit Work.
You cannot change the procurement type. You cannot process
configurable materials
discontinued materials
alternative items.

Notes
Transfer
You should always specify the network NUMBER. The system transfers thecomponent data to be changed to the table I_COMPONENTS_CHANGE.
It is not necessary to fill all component attributes if you want tochange only a few values of an existing component and retain theremaining values.
In the update structure I_COMPONENTS_CHANGE_UPDATE you can specify theattributes whose values you want to change.
Return
In the return parameter RETURN you see an error message if an erroroccurs during processing.
After calling, you see the messages that were generated duringprocessing in the table E_MESSAGE_TABLE.
