Key performance indicators (KPI) for material creation

Dear all,

I need to define some Key Performance Indicators (KPI’s) to measure the data quality during the material creation (MM01) process. The objective is to get concrete statistics about data quality/accuracy for fields related to material from all views created with MM01 (basic data, classification, unit of measure...).

I would like to get your expertise on how to measure these KPI’s : which transactions, table (...) to use ?

I have already few ideas :

-Table CDHDR

-Transaction MM04

-Create “checkpoints“ into the workflow for material creation (ZWF01)

Do you have any other idea in mind?

I am open for all advices: transaction, table, process, approach…

Thanks in advance for your help !
