Hi Johan,
Since 2006 never seen such delays in FMS so i belive it can be fixed in future.
We are migrating to HANA one of our customer which use Invoice and Payment document as let's say "Customer Checkout" functionality that's why in this process time is money.
On the document there are like 10 FMS on line side(both standard and UDF)
1.Document opens in 6 sec!
2.Adding single line takes 4 sec!
Such delays are just not accetable.
I'll wait until patch 11 since there might be some performance fixes.
Second option is to move FMS to UI but as we know we cannot use DBDataSorce so performance can be even slower.
BTW. I checked Hana trace and it seems that every FMS is fired 3 times - do not know if it's standard behavior - but for me it's suspicious.
Trace in attachment, search SELECT 1 FROM DUMMY
