I have one quastion. do anyone know how I can remove a default checked field?
In this case the field name is 'Value' and exist in SalesTable as DefaultDimension. The field in Salestable is not mandatory and in AxSalesTable class I added into (just in case) initMandatoryFieldsExemptionList() as well as I unchecked from the Table 'AifDataPolicy' which stored the flag but in the grid is still checked and disable as control.
Set property 'Fields\Dynamic' on your SalesTable datasourse to 'No' and delete field DefaultDimension
from field list. After that refresh your service.
