What are the changes to be done on BW end during hardware change of source system?

Hello Gurus,

There is some hardware changes happening and I need help in certain things which I need to do from BW point of view.  First of all, I have attached a figure showing my system landscape.  I would kindly request you to go though the fig first.

For QA, initially we were using AG3 as the source system, now they have made the hardware changes, made a system copy of AG3 into the new system AEQ.  We have connected our BW QA system to this new system AEQ.  Now when I check the system, there are no data in set up tables (I am using SD and MM), but there are data in tables.  But when I replicate data sources from AEQ to BW QA, the existing transformations and DTPs will disappear. So, that left me with 2 options-

1. Either transport old transformation and DTP from BW DEV to BW QA

2. Or create new transformation and DTP in BW QA system.

Can you experts please suggest me what should be the solution?

Also, please note that, the basis team started the hardware changes with ECC QA system for some reason.  Once ECC QA is fine, they are planning to make the changes in ECC DEV system (from AG2 to AED).  Currently, AG2 is connected to BW DEV and AEQ is connected to BW QA.

Can you please suggest me whether there will be any issue if we opt to transport transformation and DTP from BW DEV to BW QA when BW DEV is still connected to old source system?  Or, is there any other easy way to sort this out? Please suggest?

Thanks a lot

Rakesh

Hi,

1. Either transport old transformation and DTP from BW DEV to BW QA?

Yes, better to transport from bw dev to bw qa

2. Or create new transformation and DTP in BW QA system?

at BW Quality, creation may not be possible. Better to transport from bw dev to bwq.

or use standard abap program to activate transformations and dtp.

When changes are applying at source then you just need to take care the delta queues

clear all queues by running related V3 jobs and delta info packs. make them as 0 count.

once basis team was done changes later try to check your delta loads at bwq .

Hi,

As I mentioned, this is not a system upgrade, rather they have changed the old system hardware to new.  System ID has changed.  So, when I am replicating the data sources, the transformation and dtp are not inactive, but it disappeared due to the source system change.  So, we cant use the program to activate as you mentioned.  I have to either transport or create new.

Also, I am not much worried about the data loading part.  Anyway i have to start a fresh load since there are no data in set up tables, and it wont affect much coz of low volume of data.

My doubt is that whether there is any other possible solution to this rather than creating or transporting the objects?

Once basis done required changes to new systems, you just start loading data to bwq.

There is no way, we have only two options

1. activation thru program or create them if allowed.

2. thru transports.


Thanks
