A number of errors can occur when store orders are processed. Examples of errors are listed below:

• The article ID or the quantity is missing.

• A purchase order or a purchase requisition is to be created, but the source of supply, the purchasing organization or the unit of measure is missing.

• The article is not contained in the assortment list of the store.

• The master data has not been sufficiently maintained.

You can use a number of tools (such as the POS interface monitor) to analyze and correct these problems.

The inbound processing status can be analyzed using ALE tools. After technical problems have been solved, processing can be repeated.

The POS interface monitor is an error tracking mechanism that enables you to analyze errors. You can limit your selection by date, store or document category.

The following information is available in POS inbound processing for the store order:

• If an intermediate document (IDoc) is not successfully processed, the system issues information, error, or warning messages relating to the errors. You can configure your system in such a way that information and warning messages are recorded in a log. This can be useful during a test phase, for example.

• For the IDocs that are successfully processed, a list is displayed containing the reference number of the store order and the numbers of the documents (for example, purchase order number) created for every IDoc. You can then branch to a display of the documents created.

To use this function, you must have assigned users to workflow tasks. Items that are incorrect are automatically sent as work items to the SAPmail inbox of the employee concerned.

Depending on the type of error that occurred in the order item and on the required document, a worklist is created for the employee responsible.

To remove the source of an error, the following activities are necessary:

• Change or create the necessary Customizing settings

• Change or create the necessary master data

• Maintain the data for processing the workflow tasks

• Delete the item that contains an error
