Hi sairam,

NAST table is the communications interface between the Transaction and the Driver program.

It holds the information of transaction fields to trasfer into the driver program.

Yes. But these are not stored in the databse until and unless the output was issued succesfully.

I Don't understadn what your requirement is , but the standard procedure is this.

for example take Purchase order.

Me21n is the transaction.

When you save the purchase order, an output type which is attached to the ME21n transaction will trigger the PO Output driver program. The data in the ME21n transaction is transferred to the PO Driver program in NAST structure.

Once the PO's outpt is issued succesfully, NAST table will be updated with the PO Number as Object Key. for that particular Output type.
