Re: Use existing Masterdata attribute to create new one
It's a matter of pseudo attribute.
In your custom.xml, for your masterdata class, let add the following pseudo attribute:
...
<Attribute>CUSTOM_ATTRIBUTE
<IsPseudoAttribute>true</IsPseudoAttribute>
<DisplayName>Custom attribute</DisplayName>
<BusinessObjectClass>com.osm.datamgmt.biz.ExpressionAttribute</BusinessObjectClass>
<Expression>'http://docsNNN.NNN.com/parts/%NAME%'</Expression>
</Attribute>
…
This piece of XML declare a pseudo attribute which value is calculaded as the Expression. The resulting value is not stored in the database, but displayed anytime you're viewing your masterdata.
