IBP-Order-Based Planning: Error of External data source generation failed for planning set

[former_member821689]

Hello Everyone,

I was getting one error as mentioned "External data source generation failed for planning set SAP7Planning Area".

This error is coming after I have assigned a custom attribute to a standard planning level PERPRODLOCDEMAND as root attribute. Any resolution to overcome this inconsistency?

Regards,

Technically its not possible to assign any custom attribute as root attribute here in this planning level. All root attributes should have a reference to a data source
