New BOM Items ordered not retained on click ofUpdate in BOB (OOB) shop

Hello Experts,

We are using BOM material in our Business Process. Per Business requirement, the BOM sub-items are not required to be displayed on the Order Page of ISA webshop in OOB scenario.

Hence we have set the parameter "ui.fields.order.bomExplosion"to 'hidden' in XCM Setting.screenshot attached.

After making this change, we are experiencing the issue where we are not able to add any new BOM items to existing Orders, especially in the scenario where all blank line items are filled in with new BOM Products. When we click on Update, the new items are not retained and disappear.

Help is very much appriciated.

Regards,

Satish B
