Re: MRP Dates Education

Al,

There could be several sources to your problem, but the most likely is that the
first few times the item is planned requirements are getting created earlier
than the effectivety date of the components on the BOM. The BOM effective date
defaults to date of entry. If in planning the parent, the components end up
being scheduled before 'today' and the bill was entered today, 'effectively' no
components exist and nothing will be planned. As you screw around and plot and
plan, and days go by and the MPS horizon pushes orders out further, suddenly
bills become effective and planning works, I doubt playing with planning dates
has anything to do with it. If you just back date the effective dates of new
assemblies you should be fine.

The default of today for bill changes is entirely reasonable. However for new
assemblies the default should be back dated to prevent the chaos you are seeing.
