In the past, there were some issues regarding the dunning statistics display in the dunning proposal (transaction FPVA) or dunning activity run (transaction FPVB). Either the dunning statistics were completely missing or the dunning statistics were incomplete.
There are correction notes for the missing dunning statistics. You will find more information in Knowledge Base Article 2037520.
If you use parallel processing, you may only see incomplete dunning statistics. Please note that the dunning statistics are written per job and the total dunning statistics is not created by default. There is a work-around which you’ll find in Knowledge Base Article 2077157.
Attention: Regarding the dunning statistics in the dunning activity run: in a productive system, a dunning notice should only be created in a correspondence container (Function module ISU_DUNNING_PR_CORR_CONT_0350). Printing a dunning notice directly from the dunning activity run may only be used for test purposes.
Therefore, in the SAP standard system the dunning statistics are displayed in the dunning proposal run only and the standard will not display the dunning statistics in dunning activity run.
