title: Dynamics CRM 4.0 Picklist Mapping
body: <p>I have been asked to make some customisation changes to our Dynamics CRM 4.0 system and I am struggling with a key part of the changes.</p>
  
  <p>There is a picklist called "CompanyType" defined on the Companies entity and I need to display the selected value of this Picklist on the Opportunity entity's data entry form in a read-only state.</p>
  
  <p>There is a predefined system 1:N relationship between Company and Opportunity called "Potential Customer".</p>
  
  <p>I have researched this for some time and I have followed the following steps so far:</p>
  
  <ol>
  <li><p>I created an identical attribute called "RelatedCompanyType" on the Opportunity entity,  making sure that all it's picklist values matched those of the "CompanyType" picklist.</p></li>
  <li><p>I added a new mapping to the existing "Potential Customer" relationship,  mapping the picklist attribute "CompanyType" to the picklist attribute "RelatedCompanyType".</p></li>
  <li><p>I Saved and published bothe the Company and Opportunity entities.</p></li>
  </ol>
  
  <p>Having done this the value still does not map and the picklist on the Opportunity, whether new or existing, remains blank despite a value being set on the Company.</p>
  
  <p>I have been through the mappings again to make sure this attribute is not mapped twice and now I am at a loss.   Any help would be greatly appreciated.</p>
  
  <p>Thanks</p>
