Recently we have performed BW & SCM system refresh from PRD, once after the post steps Process chains were not working & throwing below error – “Variant does not exists”
To resolve the inconsistencies in post steps, you need to implement SAP note – 1455417
According to note 1455417, execute the report SA38 – RS_FIND_JOBS_WITHOUT_VARIANT in your system. This would remove all the inconsistent job entries & inform the BW team to run the process chains again.
However in some cases if the above report is not able to clean the variant then you need to create Z report given in the SAP note “Z_FIND_JOBS_WITHOUT_VARIANT” & run on the system to clean up the inconsistent entries.
Let me know if this solution helps you.
