Namespace change during a BW/4 Shell Conversion

[SudhanshuSurma]

Hi All,

Would anyone please share their experiences with automatic namespace conversion in the target system during a BW/4 Shell Conversion?

If it is possible via the Transfer/Conversion Tool, to what level does the namespace conversion happen automatically? For example, do the info-object & info-provider references/look-ups appearing in info-area / data-models / programs / routines also get converted to the new target namespace automatically?

By namespace conversion we mean, if the source system object has a technical name “/ABC/BW_Object” the target should have “/DEF/BW_Object”

In a SAP Webinar hosted in June, though the content slides said namespace conversion is possible via the tool, when we put a question if they had done it successfully, their reply was that they hadn't tried it themselves.

So would welcome any feedback from those who have attempted Shell Conversion and namespace conversion successfully. Thanks in advance!

Hello Sudhanshu,

It depends. If you leave the objects unchanged you don't need to change any programs.

If you use standard read functionalities, e. g. read from DSO within transformations, this is also considered. If the DSO-name is changed during the scope collection, the DSO within the transformation will also be changed.

InfoObjects are the heart of the BW system. They are used everywhere and if you start changing them it will have impact on the metadata structures and data-structures, incl. queries and reports.

In our case since we wish to set up (via shell conversion) a replica-BW system for a group company, we are expected to perform a namespace conversion, i.e. if the source system object has a technical name “/ABC/BW_Object” the target should have “/DEF/BW_Object”, to reflect the group company initials. Hence, we will have a lot of manual adjustments, if the conversion tool doesn't take care of this conversion automatically. Thanks for sharing your views Eduard.

Hi,

Using the Shell Conversion technical names of ODSO, CUBE, MPRO can be changed.

InfoObjects can not be changed.

Thanks for your feedback Eduard. So this means a lot of manual adjustments required during a conversion, e.g. renaming all referred BW objects (incl. IOs) in programs, transformation routines etc.

Hi @eduard.schoonbrood, maybe you have some ideas for us? 🙂
