Hi,

Did you try bringing it to SAP?

Thank you.

minimalas possible.) The setup of tables I’m using with this sort of thing are like the following example:

working,which I tested with direct SQL commands: after inserting a row (with the CATEGORYNUM not specified in the
INSERT),if I SELECT currval(‘GEN_CATEGORY’), it gives me the correct value, which is also what got saved in that
column.
