  • Hello caetano,


    Its nice reference to all MRP related queries.I also have almost same list for ready reference and it proved helpful many times. warm regards for your sharing spirit.


    Best Regards,

    • Thanks for your feebadk Dee Joy.

      I have shared this list because I see many users opening threads with questions that can be found on these notes.

      I hope that it can be useful for them!

      • Thanks Caetano. This will be useful. It’s always nice to have a quick reference to the FAQ notes. They have a lot of great information but are not always easy to find, especially if you don’t know exactly what you are looking for.

  • Hi Caetano,

    This is very useful and helpful. Generally I maintain a master sheet of useful notes for my ready reference. With time they can easily be remembered and used when situations arise. Today I was searching in SAP support portal and found out few useful composite notes on ATP checks. This kind of documentation is always helpful because it directly provides some useful key points.

    A big thank you and cheers!


    All the best,


  • Very useful and a handy ‘go-to’ reference Caetano.


    Wish that such quick reference docs have a ‘Pinned-Post’ option in SCN like it is in some sites. As many posts come in these get buried over and new comers to the forum may not find this easily. And things will be back to square one with people asking the same question.

    Presume from your ways of working and the way you hit us with the useful notes you should be from the SAP Active Global Support team.
