Diagnosis
In the InfoCube update, data of InfoSource &V1& from source system &V2&is accessed and read; this data is in database table &V4& in the PSA.To allow optimum performance, a database index is generated by theupdate as necessary.
In your case, the generation supplied return code &V3&:
0 : No generation necessary, index already exists.
1 : Index was successfully generated.
>1: An error occurred while the index was being generated.

System Response
If an error occurred during generation of the index, this reducesperformance, which means that the PSA cannot be read as efficientlyduring the update. This can lead to long run times.

Procedure
If an error occurred during generation of the index, you may be able todetermine the cause using transaction SE11 to view the activation logfor index 917 of Table &V4&.
