Dear all,
we had some problems getting currency conversion to work and I thought the root cause are the wrong definitions of the above mentioned tables in HANA.
But the reason for our problem was that besides the above mentioned tables these tables are also required: TCURW, TCURT, TCUR.
Quite strange that these three tables are not mentioned in the SAP course documentation TZH300 (collection 96), page 251 as well as in the book "SAP HANA - An introduction", page 304.
Best regards,
Karsten
