SR-F  "Reprint S/R Invoices" is working in a very funky manner!
 
If I put in one customer (from BEAMAR TO BEAMAR) before it prints anything I have to go through several Info messages  That say "Customer "xxxxxx sp " could not be found.  This customer's invoices will not be printed."   Then I get a print  of all invoices for that customer, not just S/R  invoices.  
If I ask for a spread of customers, for instance from ALLMAR TO BEAMAR,  I get the same info messages as before, as well as a new message that says "An Inventory record was not found for the product 2300005 from S/R 5553.  Please correct before continuing."  Then the program closes. The trouble is there is no S/R #5553, and the closed SO# 5553 has no product 2300005 on it.
These two  searches work in SO-F, Reprint Invoices, which prints the S/R invoices as well as regular invoices.  
I was trying SR-F because I was hoping that SR-F would only print  S/R invoices.
