Your created mappings will not show until changing default Cash Flow Mapper Positions to right values.
Go to Cash Flow Mapper list, change each Position fields in Cash Flow Mappers.
- Operating Activities position to 1
- Investing Activities position to 2
- and Financing Activities position to 3.
Please check Cash Flow Statement again after changing these values.
I’ve tested and worked in ERPNext version 13.33.0. Thanks.
