Evaluation of DBRW Formula in VBA
Dear Experts,
I’m currently working on some automation functions for TM1 in Excel/VBA.
For some purpose I would like to pass on the result of a DBRW Formula to a VBA variable.
I cannot simply us the cell value, as the DBRW Formula could be part of another calculation within that cell.
Example:
=DBRW($B$1;$B$2;$B$3;$B$4;$B$5;$B$6;$B$7;$B$8;B$11;$A12) * 2
Would anyone be able to tell me how to evaluate the DBRW?
Any help is highly appreciated!

Re: Evaluation of DBRW Formula in VBA
Like most of the TM1 functions you can use Application.Run("DBRW" , Arg1 , Arg2, etc)

Re: Evaluation of DBRW Formula in VBA
For simple formulas you can strip out the dbrw based on *, / , +,  after the closing bracket using Instr.
More complex formulas will require a some code or function to work out the positions of the opening and closing brackets of the the DBRW so it can be stripped out using those positions.
x = InStr(1, Range("A10").Formula, "*")
If x > 0 Then
y = Mid(Range("A10").Formula, 1, x  1)
result= Application.Evaluate(y)
End If

Steve, thanks for your help with this. That was exactly what I had tried unsuccessfully.
However your post helped me understanding that my mistake was somewhere else:
I had tried:
TM1Result = Application.Run(FType, TM1Parameters)
with "FType" containing the type of formula (e.g. DBRW or DBRA) and
with "TM1Parameters" containing the parameters as string (e.g. "SERVER:CUBE,EUR,Turnover,ACT,Worldwide,....")
I now moved all parameters to an array and it works:
TM1Result = Application.Run(FType, aParameters(0), aParameters(1),....,aParameters(10) )
QUESTION: The number of parameters can change, depending on the number of dimensions of the cube.
Is there a way to evalute the DBRW with a dynamic range of parameters?

Re: Evaluation of DBRW Formula in VBA
You have to do the hard work of splitting up the formula in pieces, one argument is 1 piece, and work from there.
Watch out for arguments that are text but contain the separator for arguments, like a comma in the name of an element.
The TM1 Tools addin has code for this, have a look at it, here on the forum.

Re: Evaluation of DBRW Formula in VBA
Hi Wim,
I already split the formula into pieces (with the help of code from the addin) and now I have an array (see below) with all arguments.
However the array lengh can be varying, depending on the number of dimension in the queried cube.
I found a solution for my problem today:
With a "select case" I can evaluate the DBRW Formula while considering the needed amount of arguments.
(in "numArgs" I have the length of the array)
Select Case numArgs
Case 2
TM1Result = Application.Run(FType, argsArrayValue(0), argsArrayValue(1), argsArrayValue(2))
Case 3
TM1Result = Application.Run(FType, argsArrayValue(0), argsArrayValue(1), argsArrayValue(2), argsArrayValue(3))
Case 4
TM1Result = Application.Run(FType, argsArrayValue(0), argsArrayValue(1), argsArrayValue(2), argsArrayValue(3), argsArrayValue(4))
Case 5
TM1Result = Application.Run(FType, argsArrayValue(0), argsArrayValue(1), argsArrayValue(2), argsArrayValue(3), argsArrayValue(4), argsArrayValue(5))
etc...
But this is no elegant solution.
I thought that there probably would be a better solution for calling a function with variable amount of arguments....
Is is not??
Many Thanks for your comments!

Re: Evaluation of DBRW Formula in VBA
Try:
sDBFormula = "DBRW("
For i = 0 To numArgs
sDBFormula = sDBFormula & """" & Application.Evaluate(argsArrayValue(i)) & ""","
Next i
sDBFormula = Mid(sDBFormula, 1, Len(sDBFormula)  1) & ")"
myValue = Application.Evaluate(sDBFormula)
You may have to include/exclude the quotes for each of the arguments in the above depending in how you split the arguments.
sDBFormula = "DBRW("
For i = 0 To numArgs
sDBFormula = sDBFormula & """" & Application.Evaluate(argsArrayValue(i)) & ""","
Next i
sDBFormula = Mid(sDBFormula, 1, Len(sDBFormula)  1) & ")"
myValue = Application.Evaluate(sDBFormula)

Re: Evaluation of DBRW Formula in VBA
Thank you, jrizk,
That was helpful!
Using the Evaluate Method helped:
TM1VBAString = FType & "(" & Chr(34) & Join(argsArrayValue, Chr(34) & "," & Chr(34)) & Chr(34) & ")"
TM1Result = Application.Evaluate(TM1VBAString)
Just using the JOIN instead of For...next.
