I am very, very, very new to CRM, but not new to development. I hope this post will allow me to ask a question that I have researched for weeks but have not been able to find anything resembling on what I am trying to accomplish. I am sure it is simple because all the examples I see are for situations far more complex than I am asking.
I have an Entity A, which has an N:N relationship to Contact. I have another Entity B which relates to the Entity A/Contact combination. I have a Subgrid on Contact and when I Add New Entity B, the form opens. The Contact automatically populates. The Entity A lookup is set to only show Entity A records that relate to the Contact. In most instances, there is only one value in the Entity A lookup. I would like to know how to autopopulate the Entity A lookup with the only value when only one values is possible.
Please do not tell me "it can be done with workflow, javascript, or a plugin" as I wouldn't know where to begin. I would think this is a simple request, however, it seems to be something only I have asked.

Thank you. It is much more readable without all the escapes for quotes too. I did have to modify the variable name contactID, but finally got it working. I have 3 more pages to update with the same logic, its the only code I have to write for the app so far. My first CRM app!! Thanks again!
Hi Marsox,
Seems in your fetch XML you have not assigned #contactid# in the condition attribute. I have rewrite your fetchXML , you just need to assign the GUID of contactid. Hope this helps.
Try with this -

I received an internal server error message, have no idea how to debug it. The problem is how to set the Current Contact Id

I looked at the article, but I do not understand it. Where would I put that code to run? I am very, very, very, new to CRM. I have put in forms and relationships, but ZERO coding in it. I have the Fetch XML and the Web API code. That example code in the link does not appear to be JavaScript.
When trying to use the Fetch XML, I went into my Entity A and could not find the Contacts in related entities, even though I created the N:N relationship, so I am not sure what Fetch XML I want to generate, since I am seeking a list of Entity A(s) associated with the current Contact.
I was able to figure out that I needed to set the Relationship to visible. Now when I open the Advanced Find, I can choose Contacts, but there is no option to set the Current Contact.
Hi Marsox,
As you are going to need to use Web Api to retrieve this information, I recommend that you download CRM Rest Builder in order to help you generate Api calls and retrieve the results that you want.
After you get the results, you should be able to use the code that Goutam specified below.
Hope this helps.
Thank you. The lookup may not always have just one value. I only want to set it when there is one value in it.
Hi Marsox,
As lookup field does not contain default value so you need get the value first using fetchXML of the particular lookup entity.
You can check below reference how to retrieve data using fetch XML.
You can build your fetchXML by using Advanced find in CRM.
Once you retrieve the data from lookup entity you can set field value by below way.
function setLookUp(){
var lookupValue = new Array();
lookupValue[0] = new Object();
lookupValue[0].id = "16C0C201-F1B9-E111-9361-B8AC6F88836B"; // Guid Of That Look Up
lookupValue[0].name = "Client"; // Name Of That Look Up
lookupValue[0].entityType = "contact"; // Entity Name Of That Look Up
Xrm.Page.getAttribute("new_jobcentrecontacttype").setValue(lookupValue);
}
Hope this helps.
Hi Marsox,
There is no default value option for a lookup. This is something that you would have to customize in the system, and as you already can imagine, it can be done using one of the methods that you are looking for.
I would suggest using webapi to retrieve the value of the that you are looking for, and then calling the setValue function of the attribute class (Xrm.Page.getAttribute(attributeName).setValue(lookupValue))
I am not sure if there is a third party solution that will enable you to do this automatically. Haven't seen one.
I hope you get a different answer, but I doubt there is.
Good luck.
