error in roaming.reg pipeline

Hi All,
roaming.reg(BRM 7.4) pipeline display following error.

ifw.Pipelines.

TAPCorrectionPipeline.Functions.Processing.FunctionPool.BusinessMapping.Module
Destination     :
Message         : ERR_CREATE_SCRIPT
Arguments       : BusinessMapping
compilation failed

State           : false
Severity        : CRITICAL
Thread  : 2582483616

roaming.reg is
           BusinessMapping
           {
             ModuleName = FCT_IScript
             Module
             {
               Active = True
               Source = FILE
               Scripts
               {
                 BusinessMapping
                 {
                   FileName =./iScriptLib/iScriptLib_Roaming/ISC_TAP_0311_InMap.isc
                 }
               }
             }

i didn't change iscript and irule, just test and verify default configuration.
Still didn't run irules2db.pl as perl error to apply validation rules for the roaming incollect and outcollect processes. Anyone have any idea about root cause, solution? Please share your experience.
