Customer Inquiry – Incoming 
Definition
A customer request to a company for a quotation or sales information that is not binding.
The request can refer to materials or services, conditions, and, if necessary, delivery deadlines. The materials are either identified by the material number orthe Global Trade Item Number (GTIN).
The inquiry is accepted by the sales area, which is then responsible for any further processing.
Use
EAN.UCC/GS1 Compliance adds the following new features to the existing mySAP ERP processes:
In the IDocs, a material number is determined from a GTIN and from additional information, using determination logic.
A simulation program enables a material number to be determined from a GTIN and from additional information. This material number can be manually used in standard transactions.
This enables the material-related processes to be carried out in the same way as before.
Structure
A customer inquiry comprises one or more items that contain the requested quantity of a material or service.
The total quantity of an inquiry item can be subdivided in the schedule lines into various partial quantities with the relevant delivery dates.
Items can be organized hierarchically, which enables batches to be differentiated or bills of material to be exploded.
The conditions valid for the items are listed in the item conditions. They can be derived from the overall document condition.
Integration
In addition to defining the customer as the sold-to party, you can specify various partner roles (such as ship-to party) for the other business partners.
