Relate command¶

Include: Use Db\DBCommands.pkg

Current behavior¶

The standalone Relate command from DataFlex Windows global-buffer code is not part of the TechStack Command API.

Data Dictionaries use entity Add_Relation metadata and Set DDO_Server connections to maintain related DD state during normal DD operations.

Porting¶

• Remove standalone Relate calls from command-style procedures.
• Ensure parent and child DD objects exist.
• Ensure the child DD has Set DDO_Server to oParentDD and the entity relationship exists.

Example¶

Object oCustomerDD is a cCustomerDataDictionary
End_Object

Object oOrderHeaderDD is a cOrderHeaderDataDictionary
    Set DDO_Server to oCustomerDD
End_Object

Clear oOrderHeaderDD
Move 1001 to oOrderHeaderDD.Order_Number
Find EQ oOrderHeaderDD.Order_Number
