Hello Experts,

is there a way to copy an Entity in C# without knowing the fields?

I will make a Workflow Step where i can copy or clone every Entity in CRM.

Kind Regards,

Léon

Remove reference on Microsoft.Xrm.Client. This assembly is not available in the sandbox.

This is my code and the "Clone" extentsion only exist in Microsoft.Xrm.Client.

// Seminar ermitteln Entity Seminar = service.Retrieve(rref.LogicalName, rref.Id, new ColumnSet(true)); EntityReference Id = Seminar.ToEntityReference(); //Record klonen Entity newSeminar = EntityExtensions.Clone(Seminar, false); Seminar.Id = Guid.Empty; //service.Create(newRecord); tracingService.Trace(Convert.ToString(newSeminar.LogicalName)); QueryExpression query = new QueryExpression("mrd_seminarinhalt"); query.Criteria.AddCondition("mrd_ak_seminarid", ConditionOperator.Equal, Id); // Query ausfürhen EntityCollection retrieveedxpan = service.RetrieveMultiple(query); if (retrieveedxpan.Entities.Count == 0) { // Datensätze wurden nicht gefunden tracingService.Trace("Es wurden keine Seminarinhalte gefunden!"); } else { foreach (var entity in retrieveedxpan.Entities) { //ChildRecord ermitteln Entity ChildSeminar = new Entity("mrd_seminarinhalt"); //ChildRecord klone var newChildSeminar = EntityExtensions.Clone(ChildSeminar, false); newChildSeminar.Id = Guid.Empty; tracingService.Trace(Convert.ToString(newChildSeminar.LogicalName)); //service.Create(newChildRecord); } }

I'm really sorry but you will have to write own extension replacing this "Clone" method with your own code.

If you want your code work to work you will have to follow this.

Hello,

so now i can copy entitys but that leads to antoher problem.

If i copy my Entity i want to copy the related Entitys to.

But i can't assigne the related Entity to my "Master" Entity.

The code cant find the ID from my "Master" Entity

This is my code:

//Record clone Entity CloneSeminar = Seminar; CloneSeminar.Id = Guid.Empty; CloneSeminar.Attributes.Remove("mrd_seminarid"); CloneSeminar.Attributes.Remove("mrd_ak_seminarbeginn"); CloneSeminar.Attributes.Remove("mrd_ak_seminarende"); CloneSeminar.Attributes.Remove("mrd_ak_seminarnummer"); service.Create(CloneSeminar); tracingService.Trace("Seminar wurde erstellt"); CloneSeminar.ToEntityReference(); Clone.Set(executionContext, CloneSeminar); // Retrive related Entities QueryExpression query = new QueryExpression("mrd_seminarinhalt"); query.Criteria.AddCondition("mrd_ak_seminarid", ConditionOperator.Equal, rref.Id); // Query EntityCollection retrieveedxpan = service.RetrieveMultiple(query); if (retrieveedxpan.Entities.Count == 0) { // Datensätze wurden nicht gefunden tracingService.Trace("Es wurden keine Seminarinhalte gefunden!"); } else { foreach (var entity in retrieveedxpan.Entities) { entity.Attributes.Remove("mrd_seminarinhaltid"); //CloneSeminarinhalt ermitteln Entity CloneSeminarinhalt = entity; CloneSeminarinhalt.Id = Guid.Empty; CloneSeminar.Attributes.Remove("mrd_seminarinhaltid"); CloneSeminar.Attributes.Remove("mrd_ak_seminar"); CloneSeminar.Attributes["mrd_ak_seminar"] = CloneSeminar.Id; //service.Create(CloneSeminarinhalt); tracingService.Trace(Convert.ToString(CloneSeminar.Attributes["mrd_seminarid"])); tracingService.Trace(Convert.ToString(CloneSeminarinhalt.Id)); tracingService.Trace("Seminarinhalt wurde erstellt und zugewießen"); } } }

Hi,

You can retrieve entity metadata using retrieveentityrequest and use this metadata to create entity

Following links may be helpful to you:

msdn.microsoft.com/.../microsoft.xrm.sdk.messages.retrieveentityrequest.aspx

msdn.microsoft.com/.../gg509071.aspx

Hope this helps:)

Hello,

1. When you create record using service.Create method id of record is not set automatically but it is returned as a result of call. Replace

service.Create(CloneSeminar);

with line

CloneSeminar.Id = service.Create(CloneSeminar);

2. Looks like you're working with collection in your loop but your code modifies parent record instead of child:

CloneSeminar.Attributes.Remove("mrd_seminarinhaltid");

CloneSeminar.Attributes.Remove("mrd_ak_seminar");

CloneSeminar.Attributes["mrd_ak_seminar"] = CloneSeminar.Id;

Should it be CloneSeminarinhalt instead?

3. I assume that mrd_ak_seminar is lookup field and you populate it with Guid value. During the creation it will throw an error so you should replace line

CloneSeminarinhalt.Attributes["mrd_ak_seminar"] = CloneSeminar.Id;

with line

CloneSeminarinhalt.Attributes["mrd_ak_seminar"] = CloneSeminar.ToEntityReference();
