Hello all,

I'm attempting to auto-increment a numeric field in VLWEB - I've tried to use a system variable ie '*AUTONUM___' as a default value for the field itself, but it appears this use of a system variable is not available in VLWEB. I'm interested in finding out how other people are implementing autonum-type logic in their VLWEB applications.

Thanks,
- z

Are you trying to use it on a web page or in a web component?
That will cause the "Not Supported on the Web" error. The reason being the *AUTONUM variables call a program that reads, increments and updates a data area. http://docs.lansa.com/14/en/lansa013/in ... 4_0110.htm

Therefore you need to set them in a server routine.

Code: Select all

srvroutine name(GetNumber)
field_map for(*OUTPUT) field(#wk_Packed) parameter_name(Number)
#wk_Packed := *AUTONUM15EVENTNUM
endroutine
