Re: Coding Optimization for big files

It's not clear that you need define any variables at all.
Certainly therse two aren't doing anything much

			<xsl:variable name="indexCustomer" select="@customer"/>
			<xsl:variable name="indexContract"
			select="@contract"/>

You could just use @customer and @contract in the with-param.

Although actually I don't think you want to do that either, that's just
passing the two parts of your key and then you search the whole file
again looking for that:
<xsl:value-of
select="$allSUMGr22[@customer=$pIndexCustomer][@contract=$pIndexContract]/
the slow way even though you have already made a key that indexes on
this info:


	<xsl:key name="gr22CustomerContractKey" match="/TIMM-MESSAGE/SUM/Gr22" use="concat(@customer,'|',@contract)"/>


Actually I'm confused as you don't seem to be using any of the Gr22
with the same contract and customer values except the first one.


so isn't 

<xsl:value-of
select="$allSUMGr22[@customer=$pIndexCustomer][@contract=$pIndexContract]/IMD....

just a slow way of getting back to the current node, ie the above could be

<xsl:value-of select="IMD....
