I am trying to write a Lawson web service to create a product variant but I keep getting the message "[FND0078] BCI Error: Option must be entered (WOP0702)', code: 2,002". This web service is using PDS060/A-E with PDS600/E as a related process, I am providing the following six fields to PDS600: W01OPT through W06OPT. Could you tell me if it is possible to write such web service or if there is something I am missing or better way?. I don't know if PDS600/E could be considered an scrollable window which is a constraint when writting LWS.

Thank you,
Gaston
