Is there any report in PS showing list of projects based on Person responsible/Applicant?
> Information System>Individual overviews-->Project definitions - (Txn:CN42N)
In this transaction, please go in for dynamic selection - 3 rd button (i.e after the execute button and get variant button). Opt masterdata defintion. Select applicant number, responsible person number etc. and exceute the report for a range of projects. The output will be list of projects with those applicants / responsible person.
This works for Txn:CN42 also.
Hope this meets your requirement.
