RE: Populating fields based on field name in a file

First off I have to assume that you are trying to display default values
based on the SKU.  The model below would require excessive (& hard to
maintain) coding to accomplish this or using dynamic SQL  which for this
purpose (IMO would perform very poorly...) or use a different model. 

What you *could* possibly do is this:
Create a defaults table
Keyed by MFD,MFV,EFL

With the fields:
MFD, MFV,EFL, RCDDTA(which holds the entire record defaults)

In your program define an externally defined DS of the file name (use a
prefix to make life easier...) you are grabbing defaults for
Chain the defaults file & eval the external DS with RCDDTA.

Subject: Populating fields based on field name in a file

I have a "rules" file whichcontains the following fields:
 
MFD - master field name (a field name in file MMST) MFV - value for
field name above EFL - environment file name (could be 1 of 7 for
example INVMST) EFD - environment field name (field name from file named
above i.e. DEPT) EFV - environment field value (value for field name
above)
 
the user selects a record in the MMST file (ie. SKU: 12345) and it
shoudl then populate based on the rules each fo the fields/values in the
appropriate environment file:
 
Example:
 
Rules file:
 
MFD=CORG
MFV=US
EFL=INVMST
EFD=BUYR
EFV=123
 So if the CORG field='US' in the SKU record selected from the MMST file
I want the BUYR field in INVMST to be set to 123
 
What I have "tentatively" done (and I don't like it) is shown as a
"small snippet" below, FYI In the MMST file I have 20+ fields and I have
(as of right now) 7 environment files which have multiple (5-50 approx.
fields)
 
IF MFD='CORG' and CORG (a fld in MMST) = MFV and EFD='BUYR'
eval BUYR=EFV
endif
 
My "befuddled" mind right now sees that I would ahve to this the above
for EVERY field in in every file??
 
Gotta be an easier way???????????//
