If an article with class:K* is flagged to be manufactured externally, estimated GM & expected cost will only be present if the article has a purchase price registered.

The estimated GM in the sales price folder will be empty and expected cost in the KIT will be 0 in these cases because if this is manufactured externally and there is no purchase price, the cost price is not calculated. 

The 'Is manufactured externally' field is found under the production folder on the article. 
(only on Class:K* articles).

If the flag is removed, a job will update the cost/GM during the night.
