WWI issue: function module with symbol doesn't work in conditional output

Question

Hi,
I have created a function module to be used in combination with a symbol that represents the quantity of a composition item in a composition. In some cases a average quantity is not filled and the function module calculates the quantity based on the lower and upper limit of the composition item. This function works perfectly if managed in customising with a symbol or called with a symbol in WWI. When displaying the result of the symbol in a WWI word template it shows the expected value.
However when I use the symbol with a function module (or the customised symbol with function module) in a conditional output expression, the value it represents in the expression is always equal to zero. It seems that a symbol value that is calculated using a functional module is not calculated properly when used in a conditional output expression. Setting a break in the functional module always shows the correct value, but the value as I already told, is not seen by the conditional output expression. Within the expression the value is always equal to zero.
Does anyone know if this is a known issue in WWI? Is there any solution to handle this problem? I hope anyone can help.
Thanks,
Paul

Dear Paul,
only some add on high level ideas:
if you look at:
Example: Layout of an Abridged Material Safety Data Sheet - Basic Data and Tools (EHS-BD) - SAP Library
you find the standard example of SAP for master and slave group:
2  <11BRG003 (M,SAP_EHS_1012_004;*)> ¶
3  <03EHS_L_TEXT(CED
  -SDB-01.002)> ¤
<03EHS_L_TEXT(CED-
SDB-02-07)> ¤
<03EHS_L_TEXT(CED-
SDB-02-05)> ¤
4  <11BRG002 (S:POS;*)> ¿
5 <01GESTRIDENT(I:NAM,
6  IUPAC,;*)> <11ERG002>¤

The "issue" is that you need to analyse by "line" of POS group; or precisely: it is easy to print lower, upper and average value if it exists.
In conditional output this example is shown in SAP help:
<15BIF001(AND:01G1013005VA GE 1)><01G1013005VA(;*/TL)[D:Value]>
<15CIF001><03EHS_L_TEXT(CUST-100000000000031)[D:Density is less than 1]>
<15EIF001>
I believe you need a "clever" nesting together with your customer symbol
E.g. you need first "test" the contents of the three values and decide about result
The easiest way could be to use a "table" structure as above.
Just use column header "lower"; "average"; "upper" value. Then you need to ask your self in which situation what need to printed.
If you use the table structure and you print just what is there and leave simply lower / upper limit "field" empty if it does not exists (what is bad with this?) you need only this "conditional" output topic done for average value. You could check for: if value > 0.0001 then print the value (as then there is a value); if not use the report symbol in which you calculate something. In my opinion it is worth to try it.
It is known that you can check "numeric values by using conditional output. I belive tis cintional one des work as well with the "composition" values (lwoer, upper, average),
May be this approach might help.
The "stack" examples which are discussed in SAP help and in the links shown are related to "characteristic" values of classes and not for composition ones.
C.B.
PS: If this really works you can clearly extend your solution. E.g. if lower value is empty may be print "0", If upper valus is empty may be print "100" etc. (or prepare a further costumer symbol calculating something).
