Hello MK,
The KE2S settings only has an effect on SD/FI/MM postings.
It's not possible to use KE2S for KEU5 postings.
Basically,if you wish to reduce data on the COPA tables,you have the
below options.
1.You can archive the data.
2.If all your company codes have currency A and your operating concern
currency is also A,then you can look at the possibility of deactivating
the company code currency in tcode KEA0. If the company code currency
and operating concern currency is always going to be A,then you will
get double postings.However if any company code exists with a different
currency then you may need this posting.
3.Check summarization of data as an option in KE2S to reduce the number
of documents generated in your source application,for example SD/FI/MM,
but not KEU5.
