What is the datatype of your attribute?

Check if the attribute present or not in your entity?

Use Entity.GetAttributeValue<T> instead of if( convertTodecimal(r.attribute["XXX_estdateoffirstinvoice"]) > 0 )

If that attribute is not present in the Entity instance, it will not generate an error. Instead, the method will return a “default value” of Type T, or null if T is nullable.

Hi

When the attribute value is blank it would not retrieve those attributes.

So you have to check whether the attribute is present for that record before getting the value for the same.

r.Attributes.Contains("XXX_estdateoffirstinvoice")

use this simple line:

var value = r.getAttributeValue(decimal)("XXX_estdateoffirstinvoice");

if (value > 0)

then do whatever....

save you the time to check if entity got this attribute then do this...

Hi,

The query expression will give key not found error when the value of the field is null.

So you should first check if the attribute contains value using the expression below.

foreach (var r in ec.Entities) { if(r.Attributes.Contains("XXX_estdateoffirstinvoice"))
{ if(convertTodecimal(r.Attributes["XXX_estdateoffirstinvoice"]) > 0 )
{ //Your code here } } };

Hope this helps.

Thanks Gopalan.

The issue was that most of the records had blanked attributes.
