Field help (TIMCOEHC) 

This coefficient helps with data entry. It is used to multiply the load times (preparation time, waiting time and post run time) for a standard operation, if the 'recovery of the operation data' has been confirmed.

This coefficient is not recorded in the tables. It is set to 0 (zero) when loading a routing operation. If a standard operation specified for a routing operation is modified, it is set to 1. The coefficient can be entered on the operation detail line for a new routing operation, or in the Routing operation detail screen (available from the Actions icon) when set to 1.
