Deleting Parameters and DataSets in XML CODE

Hello Together,

I built a Report based on an Analysis Project.

After removing/changing  parameters i got some error messages that the parameter values aren´t available in the datasets.

I know when i´m deleting or changing parameters the parameter already exists in the code and the dataset, too.

I´m a kind of greenhorn in handling with the xml code. After a while I succeeded in deleting those false parameters and datasets in the code. But this is a relatively  high amount of time and extremely challenging for me.

Are there any other possibilities to solve this problem?

Thanks a lot

Regards
