Maintenance Actions and User-Specific Settings of the Attribute Value Derivation Instruction Set User Interface

A system comprising:

• at least one programmable processor;
• and
• a machine-readable medium storing instructions that, when executed by the at least one programmable processor, cause the at least one programmable processor to perform operations comprising:
• providing at least one maintenance function to change at least one target attribute data value corresponding to at least one source attribute stored in a hierarchical data model and at least one instruction corresponding to the at least one source attribute;
• changing, using the at least one maintenance function, at least one target attribute data value;
• and
• generating, based on at least one user setting, a user interface for displaying the hierarchical data model and the changed at least one target attribute data value.
