Order confirmations are searched for in the following diagram:

1. Message determination begins in the procedure V1000 with the output type BA00 and the assigned access sequence 0001.
2. In the access sequence the key of the condition table 001 is determined with the sales organization 0001 and the sold-to party "company 1". The condition table is read with this key.
3. If a condition record is found, the system proposes a message default with the attributes found in table NACH.
4. The message default (which may have been edited manually) is stored after document posting as a record in table NAST. The message is given a unique number for identification purposes.
