The drop ship flow is a variation of the order-to-cash flow, where ordered items are sourced from a supplier1.
A revision on a drop ship sales order line to increase the quantity will be accepted only if the requisition is created from the drop ship sales order but the purchase order is yet to be created.This is because once the purchase order is created, the quantity on the sales order line cannot be changed2. If the purchase order is partially or fully shipped by the supplier, the sales order line is also partially or fully fulfilled and cannot be revised.

The IMPLIES keyword is used to create a configurator rule that specifies a logical implication between two expressions. The syntax of the IMPLIES keyword is:
expression1 IMPLIES expression2
This means that if expression1 is true, then expression2 must also be true.However, if expression1 is false, then expression2 can be either true or false1. In the Configurator runtime UI, the IMPLIES keyword can be used to show or hide options based on the selection of features. For example, the following rule:
'LX-Luxury Package' IMPLIES '8-way Power Driver Seat'
means that if the LX-Luxury Package feature is selected, then the 8-way Power Driver Seat option must also be selected. However, if the LX-Luxury Package feature is not selected, then the 8-way Power Driver Seat option can be either selected or not selected.
Therefore, when the LX-Luxury Package option is selected, all the options after the IMPLIES keyword will be selected, according to the constraint rules. This means that the 8-way Power Driver Seat, the 8-way Power Passenger Seat, and the Cloth options will be selected.

The Edit Configurator Model page is where you can modify the structure, rules, user interfaces, and connectors of a configurator model in Configurator Cloud. The Structure tab is where you can view and edit the features and options that make up the model structure.The Structure tab has two subtabs: Item attributes and Supplemental Structures1.
* Item attributesare the characteristics or properties of the features and options that participate in the model structure.You can use item attributes to define the behavior and appearance of the features and options, such as the default value, the display name, the data type, and the validation rules2.
* Supplemental Structuresare the additional structures that you can create and associate with the model structure. You can use supplemental structures to add more features and options to the model, such as accessories, services, or documentation.You can also use supplemental structures to create different views of the model, such as a technical view or a marketing view3.
