Spool and Purchase order number linkage table

[CHAITANYA_CHINDARKAR]

What is the linkage table for Spool and Purchase order number?

PO message output is triggered successfully, resulting in a spool being generated. Can someone help in providing table where I can find the links between the spool number to the PO number, note that TSP01 contains spool details but does not display the PO number.

If the PO output message was triggered and resulted in a spool, then the straight forward approach is check in NAST table, to link a PO number & Spool number. In NAST, field OBJKY will have your PO number and field SPONO is nothing but the spool number, if the output was triggered successfully
