XFCell number format issue in People Planning Solution

Hi,

I have setup the Global drivers in the People Planning module to be XFCell formulas, so that users can input drivers by Period/Scenario via cube views.

The formulas look like this one:

(XFCell(Cb#People_Planning:E#RU0451:P#GL1151:C#Local:S#Plan:T#|WFTime|:V#Periodic:A#PP_Acc_Driver_DE007:F#None:O#Forms:I#None:U1#None:U2#None:U3#None:U4#None:U5#None:U6#None:U7#None:U8#None))

The formula works fine as long as the value retrieved is lower than 1000. The reason is that the retrieved value is by default retrieved in the #,###.000 format, which the People Planning module doesn't like. This is an example of error message:

Summary: Error processing Data Management Step 'CalculatePlan_PLP'. Unable to execute Business Rule 'PLP_DataMgmt'. Global Driver [DE Max health insurance wage] Expression Error
Non-Numeric value found after substitution: [Expression Before Substitution =(XFCell(Cb#People_Planning:E#RU0451:P#GL1151:C#Local:S#Plan:T#|WFTime|:V#Periodic:A#PP_Acc_Driver_DE007:F#None:O#Forms:I#None:U1#None:U2#None:U3#None:U4#None:U5#None:U6#None:U7#None:U8#None)), Expression After Substitution=(56,250.000)]. Syntax error in the expression.

I have therefore tried to include a NumberFormat option in the XFCell formula, like here:

(XFCell(Cb#People_Planning:E#RU0451:P#GL1151:C#Local:S#Plan:T#|WFTime|:V#Periodic:A#PP_Acc_Driver_DE007:F#None:O#Forms:I#None:U1#None:U2#None:U3#None:U4#None:U5#None:U6#None:U7#None:U8#None, NumberFormat=####0.00))

but the People Planning seems to not like the fact that there is a coma in the string, because this is the message it gives when trying to save the formula in the Global drivers page:

"String or binary data would be truncated. The statement has been terminated."

Anybody else had the same issue? How did you solve it?

Thank you
