    Standard Lawson 4GL/COBOL Portal transactions programs can be Add-Ins driven. This is a very powerful tool to be used for mass data update. If someone develops an HTML/JAVA Portal transaction, is there any tool that can be used to mimic Add-Ins for that transaction? Such that it could be used for mass updating? I would think that fully conversational program interaction would be an issue, but beyond that? Are there any other considerations when there is a choice of using Lawson 4GL/COBOL or HTML/JAVA? 

    Thanks,

      Hi Eric Haugen - The "Doc for Developers: IOS Application Program Interfaces" document describes how to authenticate programmatically to Lawson so the web-exposed IOS APIs can be called. By doing this, you can actually use DME/AGS calls just as Add-Ins does.

      "LHC.jar provides an API for Java-based clients to programmatically
      authenticate into the Lawson system and access any web-exposed service in
      Lawson System Foundation (LSF) 9.0.x. A Lawson customer could use this
      API to, for example, interface with LSF from an application external to Lawson."

      This may be what you are looking for. Good Luck!

        Thanks Woozy. I should have stated the issue more precisely. My client already has an HTML Portal transaction in place. But now they want to be able to feed it data like they do for their 4GL Portal transactions, using Add-Ins because they sometimes have volume data. So I'm wondering if there is an Add-Ins type of application they can use to do that, passing multiple records to the the HTML transaction (and displaying back any errors). I'm thinking there isn't. This is a complex transaction and we don't have the time to reprogram it to 4GL.

        Thanks.

          Sorry I can help. I guess I'm not understanding what you are asking. In my experience, Lawson HTML Portal transactions (generally EMSS forms) typically just use AGS calls to update the application exactly like Add-Ins. If you are doing something different, maybe someone else can weigh in. Good Luck!
