FA Account Generator Error - ERROR_MESSAGE : 3135

Hi,

I customized Account generator workflow in fixed assets and created two separate process for deriving cost center. one process is working fine but other one ends with this error.  I used FAXAGTST.sql  to debug. any suggestions on how to fix it.

Account Generator is running for:

START FND_FLEX_WORKFLOW_APIS.COPY_SEGMENT_FROM_COMBINATION
Account Generator is running for:
WF ITEM = FAFLEXWF/#SYNCH
APPLICATION = 101/SQLGL
KEY FLEX = GL#/50265/5
SEGMENT_IDENTIFIER = NAME
SEGMENT = FA_COST_CTR
CCID = 161431
REPLACE_CURRENT_VALUE = FALSE
START FND_FLEX_WORKFLOW_APIS.SEGMENT_TO_INDEX
APPLICATION_ID = 101
CODE = GL#
NUM = 50265
SEGMENT IDENTIFIER = NAME/FA_COST_CTR
