Step in Generation of Run-Time Objects for Data Transfer failing

Hi,

A step/subactivity  in Generation of Run-Time Objects for Data Transfer is failing for ECC refresh.

Subactivity PC002_MT_RT_GEN failed for a custom table with syntax error "Syntax error in function module /1CADMC/OLC_250000002035513

Statement concluding with "...TYPE" ended unexpectedly"

Any help or lead to fix it will be of great help.

regards

Vinay
