Transporting Process Chain - error Source system does not exist

Question

Hi,
I tried to transport a local PC by itself (not including its main meta chain) since I have only done modifications in the local PC only. In the PC, there are PSA Processing, ODS Processing, ODS Activation, ABAP Program w/ variants and Infocube Rollup.
However, I got the following transport error: Source system does not exist
=======
Diagnosis
Source system  is not known.
System Response
The imported data for DataSource  was deleted again because the referenced source system does not exist and no mapping is defined in table RSLOGSYSMAP on an existing productive source system.
Procedure
Create the referenced source system in the Data Warehousing Workbench or define mapping to a known source system in table RSLOGSYSMAP.
You get to maintenance using Tools -> Conversion of the logical system names.
============
I have checked at the table RSLOGSYSMAP and all source system mappings are in order.
And the weird thing is, upon checking the PC itself in the transport-to box, I can activate it without any error.
FYI, we are currently upgrading to BI Accelerator. Am not sure if this could be one of the reasons.
Any inputs and tips are highly appreciated and will be rewarded with points accordingly.
Thanks

Answer 1

Hi,
This error is due to the fact that the
mapping table for the after import (RSLOGSYSMAP) is not correct maintained in PB7 system.
You need to maintain table RSLOGSYSMAP in each system
You can find the steps to do it in the attached note 127326:
o  Maintain table 'RSLOGSYSMAP' in the target BW with view
   'V_RSLOGSYSMAP' and enter as 'original source system' the logical name of the source system in the source BW and as 'target source system' the logical name of the source system in the target BW.
   This maintenance is required since it allows the correct source system reference of the InfoSources to be transported.
This source system reference in turn is absolutely necessary to activate the transfer structure.
   Example:
   Source BW with source system AAA.
   Target BW with source system BBB where the source system AAA
   corresponds to the source system BBB.
   Entry in RSLOGSYSMAP in the target BW:
   Original source system: AAA, target source system: BBB.
   Give the DDIC user in the source BW in client 000 the
   authorization profile S_RS_ALL to create BW objects.
Cheers
