Data model Modification !!!

26 Views

Hi,

I have one extractor which is running slow and its performance was to be enhanced...

( it is generic extraction with Function Module in its definition ) .

Now that i had modified the coding and its performance has increased considerbly.

For that i had created separate data source and separate Function module and of course a seperate DSO for testing. For testing i had used transformation and DTP.

But the original model has the infosurce, transfer rules and Update rule concept.

Now since testing is done and data being identical in both old and new DSO i need to include the newly modified FM logic into that of original FM. That is not a big deal.

Now the requirement is that the original model also need to be enhanced to Transforamtion DTP and not the existing Infosurce transfer rules and Update rules concept. In other words the old data source has to be migrated to RSDS datasource .

I am following the below approach to achive the same:

1) Make the original FM as a copy of new FM

2) Activate the data source in R/3

3) Replicate datasource in BW system.

4) Migrate the datasource to RSDS with export

5) create transformation and DTP

Since the fields are numerous and also the routines in it , i am thinking of making a copy of transformation.

My questions are:

1) How can i make the copy of transormations?

2) what happens to the infosurce , trasfer rules and update rules once i migrate the data source to RSDS

3) should the deeltion of objects like TRs, infosurce and Update rules generate a transport request?
