Dynamic Selection on Report Not Working

I have several reports on which the dynamic selection is not working. For instance, the report CN43N. The report is outputting all data in a year i.e it is disregarding the condition I specified in the dynamic selection fields.
Is there some configuration to make to this report so that the dynamic selection works?
Include field are only possible for fields are realte to PS table:
1. Execute Transaction SE36.
2. Logical Database Builder: PSJ
3. Choose "Extras -> Selection views".
4. Copy selection view "SAP" to "CUS".
5. Change view "CUS".
6. Go to "Tables", select the correct table, for example table ACT01 for object type "Activity".Here, you must ensure that this table is also listed under "Extras -> Dynamic selections" - only these tables can be used.
7. Double-click on the table name.
8. In the "Fields of the table", select the fields desired and allocate them to one of the "Functional groups". 9. Save.
