Handheld (legacy system ) to SAP Sales Process overview
In today scenario we have many company using SAP for tracking SD (sales & distribution ) . SAP interact with Different Legacy system (non SAP) for normal process to intregate SAP and SAP or SAP and Legacy systems .
In a handheld scenario , we have Sales represenative ideally use a HH (handheld ) device to take on Sales order and Add basic master data like new customer for any route etc . The Handheld will provide mobility in terms of the sales representatives for different manufacturing / retails companies will goto any route and take up sales orders for the customers for any routes . In case they see and meet new customer who are willing to purchase or place and order . The sales represenatative will capture sales orders for these new customers also through HH . They would have shell customer or new customer template that they will map the new customers to . Once they are verified they will be authorized to bill and supplied their Order placed . Before authorization , to avoid duplicate Customers setup for any route , the customers are placed in a block and Sales order in SAP will have Hard incompletions .
Once the Sales order is saved in HH . The Sales Rep add these HH to network ports and do a send . Once the SO from the HH are put on service network , they all are saved in a flat file which is sent to SAP via Middleware . Once the flat file reached SAP , A customized program will break up these File into Inbound IDOCS and each idoc will create a Sales orders corresponding to the Flat file created earlier ( HH related Sales order created . ) . Since interaction is with legacy system and SAP . we do send an update as an outbound idoc to HH system again for the sales rep to be aware that the Sales order has been created in SAP also . This is done through an output from SO which send the idocs to HH system . this will ensure that idocs / SO are not missed inbetween SAP and HH system and a 2 way communication is set up correctly , as required .
HH devices can be configured to be more flexible to interact to SAP for more functions , as per business requirements .
