Re: MRP Question

Daniel,

Your planning problem with the bulk items is due to the order policy code 
of (G) which is Time Periods of Supply (to see the explanation of the 
policy code go to the Item Master record for one of the bulk items with 
this code, go to the Supply screen, put the cursor on the order policy 
field and press F1. Page down until you see the G policy explanation). To 
know what value is being used for the number of time periods, check the 
value in the next field (Period Order Days) and if that field is blank, 
you need to go to the MRP System Parameters (MRP820) to see the default 
value used by your system (it will be the last line on the screen). As the 
Item Master explanation indicates, if you want that order policy code to 
order exactly to what is required, simply change the default value in 
MRP820 to (1) which will emulate the "A" (Discrete) order policy code (or 
just use the "A" order policy instead of the "G"). You may want to 
investigate why the "G" order policy is being used. If you find that each 
of the bulk items has a value in the Item Master or Facility Planning 
Records (CIC for multiple facility planning) Period Order Days field then 
the planners/buyers may have contractual arrangement with vendors for 
specific ordering periods (as an example). At least now you know why you 
are getting the results that you have been seeing. Good luck.

Subject
[BPCS-L] MRP Question






I tried to ask this question the other day but didn't explain myself in
the correct terms so I'm trying it again. Whether it's right or wrong
this is how we run our MRP. We copy the customer orders from ECL to a
temporary library called MRPTEMP that we use to run MRP. All other files
in the temporary library are blank. We do this because all we want out
of the MRP system is a breakdown of the BOM and tell us what we will
need to make the units for the orders in the temp library. 

 

For some reason we are getting some items that are not planning enough
and some that are planning too much. When I check the BOM it looks
correct. The items in question are "bulk" items that have order policy
"G." 

 

Like I mentioned before I am fairly new to BPCS and how the MRP works.
If I wanted all the items to plan exactly what we need for the orders
and no more and no less how should I have the items setup in the CICL01
file or IIML01 file.

 

Thanks,

Daniel
