Install Base Open Interface - Parallel Concurrent Workers

I have a problem with related concurrent CSIMCOPB. (EBSr12.2)

The initial situation is as follows:

-The interface tables are clean.

-Insert 4 lines in csi_instance_interface (1 parent 3 children)

-4 lines in csi_i_party_interface

-and 3 lines in csi_ii_relation_interface (only the 3 children).

then I proceed to run the import concurrent:

-Launch the process: "Install Base Open Interface - Parallel Concurrent Workers", with the necessary parameters dates, source, works number (3) , resolves id's (Y) and purges (Y) .

Internally launches the concurrent: "Open Interface Parallel Instance Creation Program", in my test the parameter "Number of Parallel Workers" is equal to 3 and then launches 3 processes as expected.
