Mapping Questions (DEC/EDI V3.1): - is there a way of finding out the number of instances for a particular record/segment ? - a FETCHED document which generates no data causes an error "Document generated nothing in Output File" and the document remains in the Current DB with status "PROCESSING". As in the environment in question the documents contain no useful data we just want to ignore them i.e produce no application file and have the document go to PURGEABLE (or maybe FAILED). Is there any way of doing this? Thanks ...colin

You could use
n = $INSTANCE(node) /* returns current instance number */
you can qualify node with an instance number as well
n = $INSTANCE(node{5})
/* returns $UNDEFINED if instance does not exist else returns instance number */

A document stuck at PROCESSING usually indicates that the mapper crashed.
Do you see any dead IMF servers (type obbmsho)?
If there are no mandatory records in the map (MIN of 1 in rec sequence)
then the document should go to purgable.

Richard, Thanks for your suggestions. Concerning my first question, I need to perform a FOR loop over all instances of a particular input record, which has a theoretical maximum of 9999 occurrences. Rather than program a FOR loop with end value 9999 I just want to check the effective records read i.e. set the end of the FOR loop to "Number of occurrences", but I see no way of doing this unless there is some undocumented function? ...colin | |||||
