  • Create an account template that details purchases and sales for certain shares (types), together with a begin- and end value
  • When copying details in the same book year, everything can be copied. In different book year, certain logic needs to be applied:
  • the end value current year needs to be copied over to end value previous year;
  • purchases and sales need to be empty again
  • if end value is zero, nothing should be copied over of the detail!
