Order Line Schedule Ship date is not cascading for PTO models - r12

Hi,

We have a PTO model and PTO item /Option class for our drop ship products that we have started using only recently on our r12.1.3 enviornment.  We also use Oracle configurator to configure PTO Models.

On Order entry work bench, when options are selected from Oracle configurator screens and passed back to Order Lines, we expect the Model line  Schedule Ship date and cascade to its child PTO Lines and populate schedule ship date there also.

This is not happening. For e.g. if change the Schedule Ship Date(SSD) for Model line to 17-SEP-2015,  its child lines (1.1.1,1.1.2 and so on) still remain unchanged.
