Anyone has faced this problem from mapping the tags to the PMML Model.

Hi ​@Thanawath.Ruangsamuth 

TrendMiner supports two-levels deep of inputs when creating tags in the Tag Builder. This means that any created tag that does not use any underlying calculated tag can be used as input. More levels of "nesting" are not supported. This level of nesting is conceptually shown in the image on the link below.

This limitation exists for performance reasons. Our R&D team is actively looking into solutions to lift this limitation in a future release.

Kind regards,
Jef
