OPIM reference part of IE_LINENAME

Hi,

I'm using the the ISO name (IE_LINENAME) as part of the SPOOL number, the issue is I don't want to see the revision of the line name (.r001 / A)

Can I use a function in the User Label area to remove part of this attribute.  EG =LEFT(IE_LINENAME,FIND("-",IE_LINENAME)-1)

Either that or is there a way to access the ISO sheet number?  I could use it to build a label manually, but can't work out how to access the sheet number.

Currently

2T14-PIP-ISO-14150-01.r001-1

Require

2T14-PIP-ISO-14150-01-1

Thanks

Ray
