Re: Write to db containing values defined by DB2

["M. Lazarus" <mlazarus@xxxxxxxx>]

Erik,

 Create a LF over the PF, specifying the fields in the file.  The 
trick is to OMIT the fields you want DB2 to automatically initialize, 
so RPG doesn't use its own rules to populate those fields.  If this 
case, just include the GRPNAME and CUSER fields.
