What is degree of parallelism in bods?

Degree Of Parallelism (DOP) is a property of a data flow that defines how many times each transform within a data flow replicates to process a parallel subset of data.

What is join rank in bods?

What is Join Rank? You can use join rank to control the order in which sources (tables or files) are joined in a dataflow. The highest ranked source is accessed first to construct the join. Best Practices for Join Ranks: Define the join rank in the Query editor.

Each reusable object has only one definition and all the calls to that object refer to that definition.

How degree of parallelism give performance in SAP bods?

The degree of parallelism (DOP) is a property of a data flow that defines how many times each transform defined in the data flow replicates for use on a parallel subset of data. If there are multiple transforms in a data flow, SAP Data Services chains them together until it reaches a merge point.
