DYNAMICS 365 HOW TO FORCE RECALCULATE ROLLUP FIELDS

In this quick Blog post, we will see how to force recalculate Rollup fields in JavaScript and C# using the below functions.

• Recalculate Rollup field in JavaScript (for account entity)
  
  function reCalculateRollupField(entityPluralName, recordGuid, rollupFieldName) {
  recordGuid = recordGuid.replace("{", "").replace("}", "");
  var requestUrl = Xrm.Page.context.getClientUrl() + "/api/data/v9.0/CalculateRollupField(Target=@tid,FieldName=@fn)?@tid={'@odata.id':'" + entityPluralName + "(" + recordGuid + ")'}&@fn='" + rollupFieldName + "'";
  var HttpReq = new XMLHttpRequest();
  // Double Check the API URL
  HttpReq.open("GET", requestUrl, true);
  HttpReq.onreadystatechange = function () {
  if (this.readyState === 4) {
  HttpReq.onreadystatechange = null;
  if (this.status === 200) {
  var results = JSON.parse(this.response);
  }
  else {
  Xrm.Utility.alertDialog(this.statusText);
  }
  }
  };
  HttpReq.send(JSON.stringify({}));
  }
  
  
• Recalculate Rollup field in C# (for account entity)
  
  public void RecalculateRollupField(Guid accountGuid, string rollupFieldName)
  {
  CalculateRollupFieldRequest request = new CalculateRollupFieldRequest
  {
  Target = new EntityReference(Account.EntityLogicalName, accountGuid), //Record to be updated
  FieldName = rollupFieldName //Rollup Field Name
  };
  CalculateRollupFieldResponse response = (CalculateRollupFieldResponse)AdminService.Execute(request);
  }
