- SAP Managed Tags:
It is known that we can maintain shipping data for order header and order item separately.
For example, suppose when I have maintained the following data, what happens when save button is clicked?
First all links to this service order is retrieved by function module CRM_GET_ALL_LINKS which works based on database table CRMD_LINK.
The link data has the following format:
The persistence of shipping data is done in function module CRM_SHIPPING_SAVE_OB:
The header guid together with all link data is put into the generic function module CRM_ORDER_UPDATE_TABLES_DETERM, which will calculate current change mode ( insert, update or delete ) by comparing object buffer with database buffer.
In this example, the determined change are two update operations as expected.
Now let's write a standalone report to perform the change on both header and item shipping data and try to interpret these two changes by our own code.
REPORT crms4_change_shipping.
