Subject: CrossCompanyAutoQuery on the form and SaveDataPerCompany on the table

I have a form similar to the salesTable.
The main-Datasource and the joined datasource are set to 
"CrossCompanyAutoQuery = true" because otherwise my filter-fields are not 
The main-table have the setting "SaveDataPerCompany = No" and the joined 
table "SaveDataPerCompany = Yes".
Now I have the problem, that I can`t create new records with the 
standard-functionality. Not in the main-datasource and not in the joined 
If I set the "CrossCompanyAutoQuery = No", then I can create new records, 
but my filter-fields are not work.

Any ideas why I can`t create records, when the datasource is set to 
"SaveDataPerCompany = Yes"?
