DataStage Error - irreconcilable constraints on the number of partitions

Fatal Error: There are irreconcilable constraints on the number of partitions of an operator: parallel <stage name>. The number of partitions is already constrained to 1, but an eSame partitioned input virtual dataset produced by parallel {natural=MOD_Nulls, synthetic="modify(0)"} has 2. 

This Error is simply Data Partitioning Error, The Stage mentioned in Error is not getting the Partition as defined for it. This is usually happen in SAME partitioning.

For resolving this, Review the Partitioning of Stage whether it is correct or not. Try to set CLEAR partitioning propagation in previous stage. This will allow new partitioning in current stage.
