Process Node shows completed but Nothing stored in DB

Hello Everyone,

PFA image of Instance of a process model which ran perfectly fine without any error. Few Details are : 

• There are 4 parallel paths in the process Model(from top to bottom respectively).
• 1st run always. --> Working Fine
• At each run either 2nd path is traversed--> Working Fine or (3rd --> Have Issue & 4th --> Working Fine) are used.

Issue: On 3rd Path, I am using the node in the red circle to store a CDT in the DB, but nothing is stored in the DB.

• The previous node(Expression rule) in the same path create that CDT which we want to store in DB.
• However if we manually open the running instance of process model & Start the encircled node by doing a right click on it, It works fine.

Kindly please explain me the root cause for this & suggest what I can do to overcome this issue.

Thanks,

Shikhar
