BW - RSA1 - ECC source system is under BW and not SAP

How to correct the source system type ?

If the source system has a reference on itself in table RSBASIDOC, it will be wronglyb categorized has BI system source and not as SAP system source on your BW system.

It's happen if you use some BW functionalities (RSA1) on your ECC source system, or just process chain (RSPC). Then, you need to delete the self reference on the source system before restoring the source system from the BW system.

To delete the self-reference on the ECC source system, you can use SE37 and execute the function module RSAP_BIW_DISCONNECT with :
• I_BIW_LOGSYS = ECC logical system name
• I_OLTP_LOGSYS = ECC logical system name
• I_FORCE_DELETE = X

Then, in RSA1 on your BW system, you can use the "Restore" functionality on the ECC source system..

On the ECC source system, to recreate your self-refence, just start RSA1 or RSPC.

If there is a error, you need to go in WE20 aznd delete standard outbound and inbound parameters on the partner LS / <source system>..

Outbound parameters :
- RSRQST
Inbound parameters :
- RSINFO
- RSSEND

Transaction : WE20, RSA1, RSPC ; Function module : RSAP_BIW_DISCONNECT
