Hi All,

I have created an embedded canvas app in model driven CRM Form.

I am updating my crm form values through the embedded canvas app -

I added the below formula on "OnDataRefresh" property of "ModelDrivenFormIntegration" so that data is updated when i hit Save on CRM Form -

Patch('DataSourceName', ModelDrivenFormIntegration.Item,
{
'Attribute 1' :Value(DataCardValue3.Text),
'Attribute 2' :Value(DataCardValue4.Text),

}
);

This works fine when i update the value of the fields such as from '600' to '700'. However the issue arises when i remove the values from the field such as from ''600" to blank " ". When the field value is blank, it does not update the ModelDrivenFormIntegration.Item and shows the previous value again as soon as i hit Save.

Also tried turning on "Formula Level Error Management", it did not work, also with this setting on my formulas stopped working

Kindly suggest any help would be appreciated.
