RSNAST00 is the program used to retrigger the output types(to make one more printout of the invoice for example). It is not specific to any application. Hence it can be used for sales order outputs, delivery outputs and invoice outputs.
 
RSNAST00 can be used only if the output was triggered for the first time in Batch mode(i.e. it is not triggered in immediate mode(4) and triggered in batch mode(1). Those kind of outputs can be triggered n number of times using RSNAST00
 
When RSNAST00, is executed , it checks the NAST table which has the data about all the outputs and select the only records which has NAST-VSZTP is equal to 1. These output lines will be yellow in colour if you see in the document. When RSNAST00 processes these records, it triggers the output and converts the line from yellow to green during which NAST-VSTAT will change from 0 to 1 for green.
 
 
You can run process output type from RSNAST00 only when the output type is set in schedule mode, its processing mode should be 1 not 4.
 
Check the settings from tcode NACE -> Condition records -> output type ->
The time should be set as 1. Now re-trigger output type from document and process it from RSNAST00, it will be processed without the error you have mentioned.
 
 
An example for Billing output:
 
Goto tcode VV32 - Fill in your own Output Type
 
At the Date/Time column, press F1, you will see these explanation.  
 
Fill in Time 1 or 2 if you wish to used the program RSNAST00.  It's work the same for all other modules.
 
Dispatch time

Technical information
The individual possibilities are:
 
Time 1: The message is processed through report program RSNAST00. This report program can be scheduled periodically or started manually.
 
Time 2: As in time 1, but the message contains an earliest processing date and a requested processing time. The message is ignored by report program RSNAST00 before the requested date.
 
Time 3: The message is selected and processed by application specific programs. Processing can take place online or in the background.
