Cluster generation error in RDF

Hi Experts,

Client have a requirement to Cluster the Causal Lift Measures in RDF. Current version is RDF-15.0.3.20 and RPAS 15.0.3.30.

Getting below error while executing the Cluster procedure through mace. Details below.

Questions:

1) Does the error only because of missing 'Cluster Hierarchy'? Note,ClusterEngine library loaded previously.

2) Same Target measure defined in POINTMEMBERSHIP and CENTROID measures parameter. Is it correct? If not, what will be the CENTROID measure intersection.

Any solution/help will be highly appreciated.

For.e.g below are the details for one Causal Lift Measure:

Source Measure:

--------------

# printMeasure -d .  -m causcalcannivsp -specs

baseint:            str_skug

db:                 data/causcalcannivsp
