Re: MRP Dates Education & effectivity dates

Hi folks,

AS400 6.0.04 MM

I have been reading your ideas on back dating the effectivity dates on the
BOM. We currently do the same because we noticed that effectivity dates were
causing problems with requirements , especially where offsets are used.  Am I
the only one who would expect the effectivity date to function in conjunction
with other BPCS functionality ?
 As it stands it leaves us with a situation where the BOM can be keyed
with an effective date of x. Then when x arrives we have to go back in and
set the effective date to x - 30 (to back date thirty days). This causes
major change control issues as our process is very tightly controlled. Does
anyone out there have a better way of getting effectivity dates to work ????

In hopeful anticipation,
Gordon.

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.
