Hi developers,
I have a system EC-CS (Sem BCS R/3 based) and I use and replicate the datasource 3EC_CS_1A in an BW System 3.1.
Is possible to use and replicate the same datasource in another system BW 7.0 in parallel ? Someone has manage a similar situation!!! There are problems of fattibility!!!! Is necessary see version patches or other!!!
Thanks in advance
Domenico
Hi Domenico!
You shouldn't experience any problem when loading data from an EC-CS OLTP application to several BW systems (two BW systems, in your scenario). Refer to <a href="https://service.sap.com/sap/support/notes/775568">SAP Note 775568 - Two and more BW systems against one OLTP system</a> (SMP login required).
In general, multiple BW connections to an OLTP system are supported. When requesting data with a <b>full</b> loading process, no special considerations need to be taken in account.
When a <b>delta</b> loading process is used, <i>the DataSources that use the <b>delta queue</b> function to process their deltas are <b>not</b> problematic, even if multiple BW systems send their delta initialization and delta requests in parallel. This affects most OLTP applications, for example, the logistic cockpit, HR, EC-CS, EC-PCA, CRM, SRM, utilities and so on.</i>
On the other hand, special care needs to be taken when using <i>extractors that determine the delta directly via a time stamp during the extraction (for example, CO-OM, FI-AR, FI-AP, FI-GL, CO-PA up to and including PI 2003.1, CFM, CML, generic delta using a time stamp)</i>. In this case, <b>parallel</b> delta/initialization runs might result in inconsistencies.
Refer to the aforementioned SAP Note for further information.
Hope it helps.
