Need help regarding "com/wm/app/tn/tspace/ReservationException"

Hi,

Can help me out for solving this issue.

I am facing one problem. The situation is as follows:
While parsing the string data, I am getting the following error:
com/wm/app/tn/tspace/ReservationException.
This is happening when I using wm.b2b.edi:convertToValues

The error log shows as below:
