We have a business scenario where we receive sales order via SOAP API (SalesOrderBulkRequest_In) via CPI and everything works fine.
Here is a part of the sales order xml file:

In the Monitoring and Error Handling App we can see that sales order is created:

Then we want to change sale order according to the documentation (SalesOrder | SAP Help Portal):

and we prepare another xml file:

After we send this xml file we get en error in Monitoring and Error Handling App:

Errors:
Function SDSLS_SOA_AIF_ORDERS_CREATE was not executed successfully
A more recent version was already processed - order 00000016760000001676 skipped.
The processing of sales order bbf31695-74f2-4e57-bc93-12971c045d33_7 stopped with errors.
What could be a problem here?

Mladen
