Addons - new versions of addon with old versions of B1

Hi guys,

Does anyone know if new versions of addons work with old versions of SAP B1?

I have a client who is asking for the latest Payment Engine (PL70) but they are on SAPB1 2005A SP01 PL12 which has the Payment Engine PL30.

My thinking is that you will need to upgrade the B1 app to PL34, if you want to use the latest addon?

or am i way out and infact the addons work independently of B1 and will therefore work on an old patch of B1?

    Yes that was my thinking also. always best to be on the same patch levels that the addons were designed for/on.. I will be interested to hear if anyone else has any ideas/thoughts?

    • Hi John,

      Patches are bug fixes and do not change functionality (unless the functionality was broken of course 😉 ). Addons communicate through the UI and DI APIs which are installed as part of the patch. Therefore, the theory should be that addons are pretty much patch independent.

      But, as has been pointed out above, it's really difficult to predict exactly what results you'll get. I guess sometimes an addon patch could have been released in order to correct a problem that was both addon and DI API related. In that case, you'd need to install the addon patch and the SBO patch.

      I never recommend you go to the latest patch until it has been around for a few weeks. However, going to a patch that is dated just prior to the addon patch release sounds like a sensible policy. In any case, testing is vital, prior to installation on a production site.

      Kind Regards,

    I will be interested to see other replies to your question, but this is my understanding.

    Add-ons are not totally dependent on B1 but they are not totally independent either. I don't think that there is any way to know if a particular add-on version will work with a particular patch level of B1. The basic advice is to keep both up-to-date.

    I don't think that there is any way that you could know for sure that an new version of an add-on would work with an old version of B1. I suppose you could try it, but i guess that there would always be the risk that the add-on was performing updating on the assumption that it was running with a higher patch of B1 and do some updating that you didn't want.

    Does SAP publish the minimum patch level for a version of an add-on?
