A quick guess: "[F:SIV]BPCINV" is text, so the customer code should be inside quotes. To isolate the problem can you simplify this temporarily to:

[F:SIV]X810STA=2 & [F:SIV]INVTYP=1 & (date$>= ([F:SIV]INVDAT + [F:SIV]YDAYSDELAY)) & [F:SIV]INVSTA=3 & ([F:SIV]BPCINV='050360')

...or should that be double quote instead of single?

In any case, if it works then expand by adding 

[F:SIV]X810STA=2 & [F:SIV]INVTYP=1 & (date$>= ([F:SIV]INVDAT + [F:SIV]YDAYSDELAY)) & [F:SIV]INVSTA=3 & ([F:SIV]BPCINV='050360' | [F:SIV]BPCINV = '100535')

And if that works then add all options back in.

Glenn,

I used your methodical approach and realized that the text field on the selection criteria table had a 120 character limit and my error was because I was exceeding that. I ended up using a different table\line on the selection criteria that (hopefully) will parse out the records I want when exporting. I also went into the screens menu and extended the character count on the text fields to 150 as the selection code was still longer than 120 even divided up.

Thanks for your help
