Communication file structure
TWL and the system modules use a designated file structure to communicate data. This structure consists of these files:
- WLET file: The WLET driver file initiates the file communications between the two systems to send or receive information.
- WLEM file: This file contains static type of information, such as product information.
- WLEH file: If order data is transmitted from the system to TWL or from TWL to the system, the header information is contained in the WLEH file. The fields that show in WL Transaction Inquiry are dependent on the order type that relates to your inquiry.
- WLEL file: If line item records for shipping or receiving activities are transmitted from TWL to the system, the WLEL file connects the line items to the WLEH records. The WLEL file contains the assigned and unassigned information for serial and lot products and components. The fields that show in WL Transaction Inquiry are dependent on the order type that relates to your inquiry.
These files operate in the background, but you can view the information contained in the files with WL Transaction Inquiry. The WL Transaction Inquiry shows these files in a format in which you can obtain specific detail about a communication event. WL Transaction Inquiry initially shows the WLET records based on criteria that you enter. You can access different windows, pages, and tabs to obtain the necessary detail.
