TNG - COST CENTRE APPLICATION DOES NOT OUTPUT COST.txt files

[annam]

THE COST.txt fails to be created from time to time, even while the service TNGDEBSWANACOSTCODE. I have discussed this problem with Odette. She requested for;
a) Memory Settings in TNG
b)The PC SPEC
c) The TNG version and Expiry date
d) The TNGDEBSWANACOSTCODE version number
