We've been asked to add a custom entity to Master Schedule Order Demands. Entity is PeggedSupplyDemand, Component is MASSCH. When I go to Entity Configuration, I get the message:  "This Entity cannot have Custom Attributes". I looked in all the documentation and community and support portal and don't see any details on what this means. Does this mean that we just can't make changes via the UI, but can using IFS Developer Studio/CUS layer, or that we can't add customizations at all?

 

It doesn’t appear in “Excluded Entities”, if that’s any help.

Hi ​@KKSloane,

ROWKEY is a pre-requisite that needs to be activated for LU to add custom fields since system creates the separate Custom Package, Custom Table and Custom view having ROWKEY as a common attribute between standard and custom table.

It is not possible to add custom fields for Entity PeggedSupplyDemand since this entity designed without ROWKEY. 

Please refer to the screenshots below for reference.

 

System gives error message if try to activate the Rowkey.

 

Though, I believe changes are possible for CUS layer using Developer Studio.

Thank you - I had just tried that. I still don’t know if this means I can do it via Developer Studio. Alas!
