Transformation's Rule Group

Hi experts,

I have problems during the valorization of some indexes in a DS->DSO transformation.

I'm trying to "reverse" a input file associating imports written in 40 columns to a specified account.

I give you an exemple: this is the format of my input file.

< key fields> <import1> <import2>....<import40>

I know that each import corresponds to an account, so in my DSO I'll have records like these:

<key fields> <account1><import1>

<key fields> <account2><import2>

...

<key fields> <account40><import40>

In the following image, you have an exemple of one of the rule of the group

Many valorizations (not dependent of the position of the column in the file)don't work, so I supposed that there's some technical limit using such an high number of rules in the group.

Can anyone help me?

Thanks in advice

Matteo

PS: I'm working on BW 7.31 Package 14 and I've already tried to implement note 2155942 with no results
