Problems with DDIC tables in a Function's signature

Question

Hi,
We're on SAP Basis 702, support pack 7.
I am trying to add a (DDIC) table to the signature of a Function in BRF+, but I have encountered 2 problems:
1. BRF+ asks me to specify the 'Table Line Type' of the table, but it refuses to recognize the structure name (ZINSTALMENTS) that I specified.
I guessed (correctly) that it was actually asking for the 'Table Type' (ZINSTALMENTS_T), not the line type.
Question 1: Do you find the 'Table Line Type' text misleading, or is it just me?
Question 2: Does this mean that we always have to wrap a structure in a table type, before we can use it to define tables in BRF+?
2. My structure ZINSTALMENTS contains three fields:
PRAMT     Types     PRAMT_KK     CURR     13     2     Payment Amount Promised
PRDAT     Types     PRODT_KK     DATS     8     0     Payment Date Promised
PRCUR     Types     WAERS     CUKY     5     0     Currency Key
..but the table structure that was transferred to BRF+ contains only the first two fields.
Question 3: Is this a bug or a feature? Has anyone else encountered this issue?
Note: field PRCUR is a currency reference field for PRAMT.
thanks for your advice
Paul

Hi Paul,
Let my analyse and comment on your text:
"I am trying to add a (DDIC) table to the signature of a Function ..."
In BRFplus you cannot add a DDIC table directly to the signature of a Function. What you can do is to create a data object of type table and add this to a function as input/context. The creation of data objects provide the option to bind to DDIC. So your table data object can be bound to a DDIC table. Your structure data objects could be bound to a DDIC structure etc. When you bind a table type it will automatically also create the line type (structure or element) and bind this as well to DDIC.
Im an not sure what exactly your problem is but maybe you expect a database table to be used for binding with a BRFplus table. This is not possible as a DB table is not a table type but defines a structure only. So you could use the DB table name in the binding of a BRFplus structure.
In case you have problems because of terminology used in the UI we should perform some tests and then we will change accordingly. Therefore I appreciate that you openly bring up the question in the forum.
"My structure ZINSTALMENTS contains three fields..."
In BRFplus there is a type AMOUNT for elementary data objects. This Amount includes a number and a currency. I assume in your case the fields PRAMT and PRCUR are included in a field of type amount with name PRAMT.
