Rebuilding of the InforSource of DBCONNECT to Oracle View

Question

Hello,
following problem:
I use DB connect to an Oracle Database to an View
It works fine.
I change the View in the Oracle Database and recompile it.
I get an Error while loading with an InfoPackage.
I have to drop the regenerate the Datasource and
I must Drop ! the InfoSource and
rebuild it completly again to be able to load again !
This stemms due to the fact that BW seems to protocol the internal state of the Oracle View, like displayed in the Oracle Dictionnary views user_views, all_views
or dba_views.
This is an inacceptable BW system behaviour and impossible for day to day    
business, development and much work, espescially if You develop a 12 or more
DBConnect View interfaces !                                                                        
Does anybody out there know how to make BW a more pleasent thing , customize it better to avoid this burden ?
Thank You !

Hello,
in all its ok, except You change the format ( number to char or char to number etc.) or the column name of  DBConnect's View or Table.
In this case You have do delete the BW Datasource and rebuild it.
It is advisable to name the DBConnect View or Table exactly as
in BW. This makes setting up of the InfoSource very easy.
Thank You
