dynamics crm 2011 - Overwrite the write method -

i overwrite write method of ds logisticspostaladress form dirpartyquickcreateform.

but have following error:

logisticspostaladdress write method if data source property changegroupmode in implicitinnerouter not supported.

thx!

the datasources node of form has property changegroupmode set none, default, or implicitinnerouter, not default, form logisticspostaladress has set so.

if set none write method available.
if set implicitinnerouter write method not available, methods writing , written are. former called before writing records , latter called after.

see how unit of work implementation form informal explanation , change group , optional record modes formal.
