RAP dump: Frontend Error: Resource not found for the segment 'Delete_mc'.

Hi experts,

I created a behavior definition, and it is working fine properly but after adding the “delete” the program dumped

This is the dump details

Frontend Error: Resource not found for the segment ‘Delete_mc’., Service: /SAP/-ZUI_AJ_SD_MAIN2_V2-0001

what does that mean and how can I fix this?
