Hello Eng Swee,
I suppose the NW patch doesn't correspond to SP level of Dev. Studio... at least, just because I didn't update it so far :)
In any case, I newer user NW as Java, so, where I can check the system's patch level?
In ABAP system it is updated through SPAM t-code... what about SAP PI? Are patches (support packages) are also downloadable from swdc? I would need more guidance.
Some more explanations on that matter will be much appreciated.
Thanks!
