Effective Date

Select the date on which to base the report or utility.

On the Material Substitution ECN Item Generation form, select the date to identify the earliest bill of material effective dates to be addressed by the material substitution change. This date determines in which BOMs the substitution should take place. For example, if you select an effective date of 5/1/02, only BOMs where the material's effective date is earlier than 5/1/02 and where the obsolete date is later than 5/1/02 will be affected by this substitution. The process, when adding a material, will always default to the ECN header's effective date. You may change the effective dates in the line item. If you do, they will not be overwritten by the header effective date. Also, the Effective date determines when the updated material ECN line will be obsolete.
