The PP-PDC interface is available as of release 4.6A. PP-PDC is an interface for R/3 Shop Floor Control. It is standardized for connecting subsystems used for entering time tickets and time events.

The interface used previously (as of release 3.0A) was called Communication Channel 2 (CC2). In comparison to the previous interface, the new interface includes an enhanced range of business functions. In addition, it has been implemented as an asynchronous SAP R/3 BAPI interface that functions without the transceiver.

Subsystems can take part in the SAP Complementary Software Program (CSP) for this interface.

For detailed information about this interface, refer to the certification documentation: R/3 Shop Floor Control: Plant Data Collection (PDC) PP-PDC.

To execute the PDC data transfer, the following requirements must be met:

• In Customizing, you define in the communication parameters

• Which data should be downloaded (work centers PP-PDC, variances, units of measure, material dependent units of measure). This setting is valid for scheduling in a background job. When transferring in the dialog, you can select the data in the selection screen.
• Whether the update of confirmations that are received is to be triggered immediately.
• Which user is informed by the system with an express mail, if an error occurs.

• Operations that are to be transferred to the subsystem must be suitable for PDC. This means that,

• The PDC active indicator has to be set in the order-dependent parameters (for each order type, plant).
• The work center of the operation has to be assigned to a subsystem via Subsystem grouping (tab page Basic data, pushbutton: Subsystem). You carry out this assignment in work center maintenance.

With the download function you can send data to a subsystem, so that input checks can be made in this subsystem. You need to download data to the subsystem to carry out checks in the subsystem. The following checks can be carried out at the subsystem level:

• Existence checks for operations
• Quantity checks

In the master data download the master data is downloaded to the subsystem, so that extensive checks can be carried out there. You can transmit the following data:

• Work centers

• Variations

• Units of measure

• Material-dependent units of measure

R/3 sends an upload request to the subsystem, asking it to transfer confirmation records to R/3.

With the upload function you transfer the confirmations from the subsystem to the R/3 system. You can set up the system so that either the confirmations are updated automatically after they have been transferred (see prerequisites) or the program CORUPROC1 is scheduled to do the update as a background job.

The scheduling of the above-mentioned programs is prepared in Customizing for Shop Floor Control: Operations ® Confirmation ® PDC Data Transfer ® Schedule Background Jobs for PP-PDC.
