Checking and Changing Data

The PSA offers you the option of checking and changing data before you update it further from the PSA table in the communication structure and in the current data target.

You can check and change data records to

• Remove update errors.

  Example

  If lower case letters or characters that are not permitted have been used in fields, you can remove this error in the PSA.

• Validate data.

  Example

  For example, if, when matching data, it was discovered that a customer should have been given free delivery for particular products, but the delivery had in fact been billed, then you can change the data record accordingly in the PSA.

You have determined the PSA transfer method in transfer rule maintenance for an InfoSource, and have loaded data into the PSA.

You have two options for checking and changing the data:

1. You can edit the data directly.

   1. In the PSA tree in the Administrator Workbench, select the request for which you want to check the data and choose  Context menu (secondary mouse button)  Edit Data .

   A dialog box is displayed in which you can select which data package and which data records you want to edit for this package.

   1. When you have made your selections choose Continue.

   The request data maintenance screen opens.

   1. Select the records you want to edit, select Change, and enter the correct data. Save the edited data records.

2. Since the data is stored in a transparent database table in the dictionary, you can change the data using ABAP programming with PSA-APIs. Use the programming for a PSA-API with complex data checks or changes to the data that occur regularly.

   Caution

   If you change the number of records for a request in the PSA, meaning adding or deleting records, a correct record count in the BW monitor is no longer guaranteed when posting or processing a request.

   Therefore, we recommend not changing the number of records for a request in the PSA.

The corrected data is now available for continued updates.
