Diagnosis
The change of the checking group you have carried out changes thesummarization of requirements, that is, if you have already createdindividual requirements records, you nowcreate summarized requirements records,with the new checking group and the other way around.

System Response
This change prevents a uniform view of the data, since from that momentindividual as well as summarized requirements records exist for one ormore materials at the same time.

Procedure
Check whether requirements records already exist for this material. Ifthis is the case und you want to ensure a uniform view of yourdatasets, you can either select or create a different checking groupwith the same summarization, or you convert the already existingdatasets. In this case, please contact your consultant.
