Description:  Each document that is posted in Contract Accounts Receivable and Payable is uniquely assigned to a reconciliation key. 
Key features:  You can create reconciliation keys in the following ways: ManuallyYou can create reconciliation keys manually. You can use reconciliation keys created in this way for any postings as long as the keys remain open. AutomaticallyIn posting transactions such as document posting, document reversal, or in account maintenance, you enter a reconciliation key. If this key does not already exist, the system asks if you want to create the key. If you confirm the query, the system creates the key automatically.Depending on the system setting, the system proposes a reconciliation key. Using a reconciliation key proposed by the system is useful if, for example, all manual postings for a given day are to be carried out with the same reconciliation key. As standard, the reconciliation key proposed is made up of the current date, the document source, and the user group. You can also use event 1113 to determine the default value.  In a payment lot or returns lot, you enter the desired reconciliation key for a payment run or dunning run (for a payment run, only the first 10 characters of the reconciliation key). Alternatively, for payment and returns lots, the system proposes the name of the lot as the reconciliation key.The system creates the reconciliation key and reserves it exclusively for the relevant object. An alternative use, such as for manual posting, is not possible.For a payment run, two characters (such as AA) are attached to the characters specified for the reconciliation key. In this way, a sufficient number of reconciliation keys is also reserved for parallel processing steps. For a mass posting run the procedure is different. Here, the system creates the reconciliation key automatically and closes it after the program run. The system proposal consists of the run date the and the run ID, in order to make the assignment to the mass run easier. The reconciliation key is created automatically from this key and the job number. In most cases the key agrees with the first document number created. Alternatively, you can enter the reconciliation key explicitly (for example, during the initial document transfer). In this case too, the system closes the reconciliation key automatically after the program run. For external postings, the reconciliation key is also assigned automatically.
