Service Level is not valid

Hi,

I am getting a message during DTR creation in TM system as "Service Level XX is not valid".

XML failed because of the above error. Service level code which is present in the XML message from ECC system is maintained in the SPRO configuration in the path SAP TM-> SCMbasis->Master Data ->Business Partner->Define Transportation Service Level codes and the corresponding mapping also done.

But still coudnt know what I am missing here. Need help on this.

Thanks in advance.

Regards,

Premalatha. S
