How to enhance R/3 communication structure

[Former Member]

Hello,

I am new to BW. I need information on how to enhance communication structure in R/3.

Also where can I learn how to use ABAP in creating user exits and start routines in BW. Is there a specific book on BW and ABAP for creating user exits or online resouce?

Even then, the communication structure is in BW.

Search this forum and there are lots of sample codes and suggestions.

Thanks

I meant communication structure in LO extraction. I want to enhance LO extract structure in R/3 with new fields not found in the present communication structure before it is extracted.

Can you also help me with where to read more on ABAP and user eixts in BW. I have just done a BW training a month ago.

Communication structure is in BW. There is no communication structure in R/3.

The best place to start for you is help.sap.com - BI and start reading the materials and if you have access to any BW system, start creating objects and play around.

If you have specific question, this site is always there to get a reply.
