Short Dump when trying to add Formula in Transformation

Hi,

I have a short dump when I try to add a formula in any transformation in sap bw.

The message of the error is (st22):

In include "CL_RSTRAN_RSFO_VERS===========CM009 ", in line 44 of program

"CL_RSTRAN_RSFO_VERS===========CP ", the following syntax errors have occurred:

L'objet de données "L_S_FIELD" ne possède aucun membre avec le nom "SUFFIX".

My configuration is :

-------> SAP BW 740 SP02

-------> BI Content 747 SP08

Best Regards,

Rafik
