I just want to know what is the significance of column "CHGMGMT_FLAG"
You will find the CHGMGMT_FLAG column when you export the Workflow Template report , for example, to an excel file since this value is not displayed when you look at the report from "view report" tab from inside Stat windows client report library window. Stat developer informed me that the value of CHGMGMT_FLAG column is automatically set to "N" in the Stat database back end table named "WRKFLW_DEFN" when the workflow is created and the value will always be "N" and should not be changed. There is no place in Stat application front end menu to enter a value for this column or change its value. The value of "N" from CHGMGMT_FLAG column from "WRKFLW_DEFN" table is used internally by Stat application code.
