Re: EPDM Issues and Concerns

Hi list!

Just want to share few notes I have compiled from MAPICS INFOR about this 
subject and I hope it helps somehow:
 
EPDM is an application that provides 'enhanced' PDM function.  It provides 
the capability to have multiple revisions of the same item number, and 
multiple bills of materials and routings for one item number.  It allows 
'generic' routings that can be attached to many end items, so that a 
change to this one routing will cause all items to be updated.  It 
provides mass maintenance capabilities.  The client interface provides the 
ability to look at information in many ways.  The capability exists to 
define multiple sites, either production or simulation.  A simulation site 
is typically used for running costing simulations.

The EPDM files are all keyed by site.  The site is typically a location in 
which manufacturing activities are performed.  Different locations that 
share manufacturing facilities or bills of material would belong to the 
same site.  A site is associated with a specific warehouse in the WHSMST 
file. 

The enterprise item file ITMENT has one record for every item number in 
use across all sites.  The released item file ITMREL has 1 record for the 
released revision of every item number.  You can only have one released 
revision of an item across all sites.  The ITEMASA, - B, -C will only be 
updated by the released revision.

The ITMRVA, -B, -C files are keyed by site, item number and revision, and 
are the equivalent of the item master files.  Each item revision has an 
equivalent item process record. ITMPRC.  You can have primary or alternate 
item process records.  You can have multiple primary item process records, 
but they must be exclusive by effectivity date....that is no effectivity 
date overlaps. 

The ITMPRC record points to the bill of material and the routing that is 
used.  If the alternate BOM id is blank, then the item 
number/site/revision is used to retrieve the record from the PSTHDR 
file....which then points to the PSTDTL file that lists all of the 
components.  If the alternate BOM id is not blank, then that value 
/site/revision is used to retrieve the record from the PSTHDR file....and 
PSTDTL file.  Different item revisions with identical bills of materials 
would use the same alternate bill of material ID.  Then one change to this 
bill would affect all item process records that reference the alternate 
bill of material ID. 

The ITMPRC record contains the routing ID and version that defines the 
routing information.  That information and site is used to retrieve the 
RTGHDR and RTGOPR record information.

The equivalent of the work center file WRKCTR is the FACMST, facility 
master file, and the key to that file is site/production facility number. 

When a manufacturing order is created, you can select the revision and/or 
process that you wish to use for the warehouse that is entered.  If no 
revision is entered, the default is *cur, which will use the current 
effective revision as of the manufacturing start date, and will use the 
BOM and routing associated with the primary process of that revision. 

At XAR6, there are some applications, such as COM and PUR that are not 
fully integrated with EPDM.  In certain cases, these applications will use 
the information contained in the item master files, which represent the 
released revision across all sites. 
 
List of EPDM files and corresponding PDM files.
EPDM file     PDM file (equivalent)
ITMRVA        ITEMASA
ITMRVB        ITEMASB
ITMRVC        ITEMASC
ITMPRC        (NEW FILE)
ITMREL        (NEW FILE)
PSTHDR        (NEW FILE) 
              See below for more information
PSTDTL        (PSTRUC)
RTGHDR        (NEW FILE) 
              See below for more information
RTGOPR        (ROUTNG)
RTGODS        (RTGDSC)
FACMST        (WRKCTR)
WRKLST        (NEW FILE)

PSTHDR contains the following fields that were in ITEMASA 
NOSLC - Number of single level components
SBQTY - Standard batch quantity

RTGHDR contains that following fields that were in ITEMASA
CUMSY - standard cumulative yield
CUMCY - current cumulative yield
NOROP - Number of routing operations
RTCHG - Routing change 

WARNING:
1) The following PDM files will no longer be used when EPDM is activated:
PSTRUC
ROUTNG
RTGDSC
WRKCTR

2) If you plan to use more than one site and / or more than one revision, 
you may need to start thinking about dealing with a strategy to deal with 
all your queries that are using ITEMASx files.
