I have restored system to previous level. I wasn't able to add SP 12 for ST-BCO in queue and SAP responded as follows:
I check the import conditions for SP 08 -> 12 and it seems SP08 has
the conditions
SP 8 ->ST,710 Add-on ST Release 710 must not be installed OR
->BI_CONT,707 Non-permitted release of add-on BI_CONT installed
The BI_CONT should be -> SAPK-707BHINBICONT SAPK-70701INBICONT but on
the SM8 system it is
BI_CONT 706 0002 SAPK-70602INBICONT Business Intelligence Content
I believe you would need to update the BI_CONT to 707 SP01 to continue
To see yourself follow the steps.
Display Define -> ST-BCO -> Display Queue Calculation (scroll of
paper Icon third from the right)
I have not yet worked on it.
