Issue in Create Session method

Hi all,

We have a requirement to create order in backend. We are using the RCOIS method (BatchValidate)to achieve the same.

We are manually inserting the Root product in the S_ORDER_ITEM table and then we are bundling it.

It works for almost all the product except for one, where we are getting "Internal Worker Error" (SBL-ISS-00120)

We figured out it was because of two constraints. The structure is as follows.

Product A(Root Product)

|_Relationship 1

     |_Product B

     |_Product C

     |_Product D

     |_Product E

|_Attribute A(No by Default)

|_Attribute B(Add by default)

The Constraint is as follows.
