The record could not be deleted because of an association exception in Dynamics 365

Recenlty while trying to delete product records, we got the below error.

The quick way to figure out which associated entity’s record could have restricted the deletion of the record, open the 1:N relationship for the entity.

Search for any Parental, Referential Restrict Delete or any System relationship that has Restrict set for Delete action.

In our case it was the System relationship of Product with Opportunity Product

With Restrict Behavior set for Delete action.

Deleting all the opportunity product record allowed us to delete the Product records.

Hope it helps..


Sample code to retrieve more than 5000 records using FetchXML in CRM


Sharing a sample code to retrieve more than 5000 records using the Fetch XML.

Version 1 :

private List<Entity> GetTotalRecordsfromFetch(string fetchXML, IOrganizationService orgService)
List<Entity> lstEntity = new List<Entity>();

int fetchCount = 5000;
int pageNumber = 1;
string pagingCookie = null;

while (true)
// Build fetchXml string with the placeholders.
string xml = this.CreateXml(fetchXML, pagingCookie, pageNumber, fetchCount);
RetrieveMultipleRequest fetchRequest = new RetrieveMultipleRequest
Query = new FetchExpression(xml)

var returnCollections = ((RetrieveMultipleResponse)orgService.Execute(fetchRequest)).EntityCollection;

if (returnCollections.Entities.Count >= 1)

if (returnCollections.MoreRecords)

results.pagingCookie = returnCollections.PagingCookie;
// If no more records in the result nodes, exit the loop.

return lstEntity;

public string CreateXml(string xml, string cookie, int page, int count)
StringReader stringReader = new StringReader(xml);
XmlTextReader reader = new XmlTextReader(stringReader);

XmlDocument doc = new XmlDocument();

XmlAttributeCollection attrs = doc.DocumentElement.Attributes;

if (cookie != null)
XmlAttribute pagingAttr = doc.CreateAttribute("paging-cookie");
pagingAttr.Value = cookie;

XmlAttribute pageAttr = doc.CreateAttribute("page");
pageAttr.Value = System.Convert.ToString(page);

XmlAttribute countAttr = doc.CreateAttribute("count");
countAttr.Value = System.Convert.ToString(count);

StringBuilder sb = new StringBuilder(1024);
StringWriter stringWriter = new StringWriter(sb);

XmlTextWriter writer = new XmlTextWriter(stringWriter);

return sb.ToString();

Version 2 :

private static List<Entity> GetTotalRecordsFetchXML(OrganizationServiceProxy orgProxy, string fetchXML)
XDocument xDocument = XDocument.Parse(fetchXML);
var fetchXmlEntity = xDocument.Root.Element("entity").ToString();

EntityCollection entityColl = new EntityCollection();
List<Entity> lstEntity = new List<Entity>();
int page = 1;

entityColl = orgProxy.RetrieveMultiple(new FetchExpression(
string.Format("<fetch version='1.0' page='{1}' paging-cookie='{0}'>" + fetchXmlEntity + "</fetch>",
SecurityElement.Escape(entityColl.PagingCookie), page++)));

while (entityColl.MoreRecords);

return lstEntity;

Hope it helps..
