Re: MRP Generation.

Chandra:

I am assuming that you have entered the Forecasts within MPS in Forecast 
Maintenance (MRP100) and that you have valid Bill of Materials entered in 
BOM500 with valid Effective and Discontinue Dates.

The parent Item for which you have entered a Forecast should be coded as a 
Master Schedule Item by placing a "M" in the MRP Code in Item Master 
Maintenance (INV100).  In this case, it will be planned during MPS Generation 
(MRP500).  Otherwise, it would be planned during MRP Explosion (MRP600).

The fact that you do NOT see any explosion of components is probably due to 
the Order Policy Code which is found in Item Master Maintenance (INV100).  If 
it is a blank, then the Item is skipped for MPS/MRP planning.  You should 
also check these values in Facility Planning Data Maintenance (MRP140).  The 
data values actually used in MRP500 and MRP600 are stored in this file (CIC). 
 They initially default from the Item Master.  However, if your Item Master 
values were blank initially, then the Facility Planning Data is probably 
blank as well.  There is a function key (F15=Copy Defaults) that you can 
press to refresh this data from the Item Master.

Hope that this helps you find the problem.  If you have any other questions, 
please let me know.
