Did you add exclusions in where clause for when cuscl is NOT null?  
When searching for the records that are null--are you saying eq to ' '?  Not
eq to null?  
Hope this helps.

Subject: help with an SQL to fix MAPICS file

Hopefully someone on the MAPICS group knows SQL enough to help me debug my 

I am having someone update Customer Class fields in our LIVE environment 
to get the data correct.  We do not have the luxury of refreshing the test 
environment frequently.   I prefer not to copy the MBBFREP from the live 
environment (ZZ) to the test environment (ZD).   What I want to do is 
simply update MBBFREP (customer master) in the test environment with the 
value of the CUSCL field from the live environment, ignoring all other 
fields and handling the possible differences between the files (customers 
added or deleted in live or in test since the last refresh). 

HERE'S THE SQL I'm trying to use:

update amflibd/mbbfrep a set a.cuscl= 
 (select b.cuscl from  amflibz/mbbfrep b where a.comno=b.comno and 
a.cusno=b.cusno and 

HERE'S THE ERROR I'm getting:

Null values not allowed in column or variable CUSCL.

I've tried adding exclusions in my where clause for when the CUSCL IS 
NULL, etc., but nothing I'm doing is working.  There are some records in 
ZZ that have blank in the customer class field, but when I SQL to find 
those with NULL values, I get nothing -- as in no records seem to contain 
NULL.   Am I doing somthing in my subquery that would cause the result 
rows to be empty?   Everything I've tried indicates there should be 

Any suggestions would be greatly appreciated.
