PowerExchange imports Long Alpha (LA) fields with a default length of 1,024 bytes. You can override this default length from the PowerExchange Navigator by editing the data map. Open the

Record

window of an Adabas file and then open the

Field Properties

dialog box for the LA field. In the

Length

field, you can enter an override value of up to 16,381.

If the Adabas field definition table (FDT) for an Adabas source or target is password-protected, the Adabas FDT password is required to connect to the Adabas source or target during a PowerCenter batch session. To enter the Adabas FDT password, edit the session in Task Developer. On the

Mapping

tab of the

Edit Tasks

dialog box, under

Sources

or

Targets

, click the Adabas source or target definition. In the right pane under

Properties

, enter the FDT password in the

ADABAS Password

attribute.

If you use Adabas 8.2.2 or later on z/OS, PowerExchange supports Adabas files that contain spanned records as data sources. A spanned record is a logical record that is composed of a single physical primary record and up to four second secondary records. Each record is stored in a separate data storage block.

If an Adabas descriptor field has the null suppression (NU) attribute, a PowerCenter workflow that accesses the field might return unexpected results. A descriptor field with the NU attribute is excluded from indexes. If a workflow attempts to perform a write based on the key field value, a SQLCODE=256 failure code or other error condition might result.
