    Hello!

    I have done extensive modifications to traditional Lawson modules, e.g. HR. I used javascripting and Design Studio, so I know my way around most of the front end components.

    I have a client who needs modifications to 5.3. PSA is not part of the standard Lawson. If I need to modify PSA, can I used Design Studio to modify the forms? OR do I use Javascript, or the PSA scripting language. Does PSA have traditional form numbers, system codes, etc? (probaly not, right?).

    Thank you.

    Robert.

      Hi Robert, modifications to PSA are quite different than modifications to tradtional Lawson modules. This was an acquired product, so it's not like the other modules. "Sprawl" is one way you could describe the PSA architecture...although I think it's more appropriate to refer to it as an n-tier implementation. Some of the code is in stored procedures in the database, some in Javascript, some in traditional Lawson COBOL modules for interfaces, etc. So, no you can't use Design Studio (unless you're trying to modify one of the base Lawson PW or ET modules used to interface...) So, my question would be "what are you trying to modify"?
      Thanks for using the LawsonGuru.com forums!

        First, thank you so much for responding. Two, my spelling is atrocious, my apologies. What a great blog site!

        For the moment, I cannot answer your questions, because I still have to win the engagement, and don't know the specifics. From the initial requirements, it seems to be the interface only. When I learn more, and have more questions, I will post again.

          It took awhile to figure it out, but I have it now. As in my post regarding CDATA and XML, javascript and html mods are found within the CDATA tags, while PSA xml structures are defined outside CDATA. Calls to the database are defined by the RESULTSET tag, and read using an A4.DATA tag found within CDATA - no process loops are required. The options are just too numbered to cover in this thread; straight SQL, stored procedures, javascript methods, binding columns just to name a few, but with patience and attention, it can be done.
