In my previous blogs I have already introduced the steps how to debug the product initial download in both CRM and ERP side. In this blog I will show you how to debug the product Delta download. Delta download only makes sense for a product in CRM system which has already been synchronized from ERP system via

initial download sometime ago. Once the material in ERP system has been changed, you can also synchronize such change into CRM system via delta download.

  • CRM system: QDD/504

  • ERP system: Q7Q/504

in ERP system, change one material which has already been downloaded to CRM system before.

for example I change its description, and type /h in command line, then click save button.

The function module CRS_MATERIAL_COLLECT_DATA is responsible to assemble the material data which are to be sent to CRM system.

the generic function module CRS_SEND_TO_SERVER is called to send the data.

The variable gt_rfcdest contains the destination name with which the material data is sent to the target CRM system. And the RFC queue name in CRM system.

then you can use tcode SMQ2 in CRM system, and you should find the queue there. The left steps to debug in CRM system is just the same as the one in how to debug initial download in CRM system.
