HOW TO TRANSFER RFC DATA USING JCO OR .NET CONNECTOR | Axel Angeli

Q: My question is on the communication protocols that support the Web
AS architecture, namely DIAG and RFC. Where can I find specifications
for these protocols?

A: If you want to transfer data through RFC, you need to make use of
the SAP provided low-level API, e.g. librfc32.dll for Intel-based
machines. To conveniently use them, you are better off using the
application-level APIs like the Java connector (JCo) and .NET
Connector...

BEST WAY TO TRANSFER A TRANSACTION | Matt Billingham

Q: If I have more than one transaction (I have 20!) to transfer,
which method should I use -- the transaction or session method -- and
why?

A: With sessions you have SAP's error handling. With call
transaction, you have to handle the records yourself...

PROS AND CONS OF MYSAP ERP VS. R/3 ENTERPRISE | Axel Angeli

Q: I'm wondering about the pros and cons of mySAP ERP 2004 vs. R/3
Enterprise. We are debating on what to use for a major project that
is in the realization phase...

A: There is nothing to debate. The recommendation cannot be anything
other than to install the very latest release available the moment
you enter the pre-go live tests...

BAPIS VS. BDCS | Matt Billingham

Q: What is the difference between LSMW, BAPI and BDC? What advantages
do they have on one another?

A: BAPI is a SAP-supplied function module with a defined interface,
which allows you to interact with various business objects. SAP
guarantees the integrity of your database for anything updated using
a BAPI. BDC is a method of driving screens programatically...

IDOCS: HOW TO PROCESS SEQUENTIALLY IN R/3 ENTERPRISE | Axel Angeli

Q: We have just updated to R/3 Enterprise from 4.0B and have
encountered a problem which doesn't appear to be covered in OSS notes
... It involves the handling of two Msg Types: CONF21 and WMMXBXY. As
in 4.0, one instance was established to support both transactions,
but processing the Msg Type CONF21 the application failed due to the
lack of resources...

A: From what I understand it seems that you have a locking issue. The
system tries to process one IDoc while another IDoc is already
blocking the material. So the problem may be occurring now in R/3
Enterprise because your new installation has more resources or is
simply faster...
