Issue in OTR creation with Numeric Range of Customer Code

Dear All,

I am facing error while creating OTR with reference to Sales order in SAP TM system. The Error message “Business partner internal ID 0000710420 does not exist” appears when I Use Customer Code as Numeric, whereas if I create customer with Alpha-Numeric, then there is no issue.

I have debugged the same and found the error is in Class “/SCMTMS/CL_TRQ_ICPY_TRQ_REQSRV” under Method “PREPARE_MD”. In this method, the system is converting the Business partner Code (Field: EXT_BP_ID) of Customer to 60 Character for Numeric Customer Code. Due to which system is not getting the KEY (Field: INT_BP_KEY) of the Business partner as shown in below screenshot:

Whereas for Alphanumeric Customer Code, system is not converting the Business partner Code to 60 Char and hence not giving error. Below is the screenshot:

Kindly advice how to resolve the issue.
