BB9564 OCL

The provided document is an OCL (Operation Control Language) program, BB9564.ocl36.txt, used on IBM midrange systems like the AS/400 (now IBM i). This program is called conditionally from the main OCL program BB956P.ocl36.txt when SWITCH2 is set to 1. It appears to be part of the rack pricing update process, likely responsible for further processing or updating pricing data. Below is an explanation of the process steps, external programs called, and tables (files) used.

Process Steps of the OCL Program BB9564

The BB9564 OCL program is concise and serves to execute an RPG (or similar) program with specified input files. Here’s a step-by-step breakdown of the process:

  1. Load the Program:

  2. // LOAD BB9564:

    • Loads the program BB9564, which is likely an RPG program or another executable on the system, responsible for processing data related to rack pricing updates.

  3. File Definitions:

  4. The program specifies two files to be used by BB9564:

    • // FILE NAME-NEWPROD,LABEL-?9?NWPROD,DISP-SHR:
    • Defines the NEWPROD file (new product or pricing file) with the label ?9?NWPROD (prefixed by the library/environment ?9?) and shared access (DISP-SHR).
    • // FILE NAME-PRCTUM,LABEL-?9?PRCTUM,DISP-SHR:
    • Defines the PRCTUM file (customer master file) with the label ?9?PRCTUM and shared access (DISP-SHR).

  5. Execute the Program:

  6. // RUN:

    • Executes the BB9564 program, which processes the input files NEWPROD and PRCTUM.

  7. Program Termination:

  8. The OCL script ends after the RUN command, with no additional logic or conditional processing defined.

Business Rules (Inferred)

Since the OCL program itself does not contain explicit business logic (it only sets up and runs BB9564), the business rules are inferred based on its context within the rack pricing update process and the files involved: 1. Purpose: - The BB9564 program likely processes or updates the NEWPROD file (generated by earlier programs like BB9563) using data from the PRCTUM customer master file, possibly to finalize pricing updates or integrate new pricing records into the customer master. 2. Input Processing: - Uses NEWPROD as the source of new pricing data (e.g., company, location, product, container, and unit of measure from BB9563). - Uses PRCTUM for customer-related data (e.g., company number, customer number, product code, container code, unit of measure). 3. Shared Access: - Both files are accessed in shared mode (DISP-SHR), indicating that multiple processes can read these files simultaneously. 4. Output: - The OCL does not specify an output file, suggesting that BB9564 either updates PRCTUM or NEWPROD in place or produces output through other means (e.g., a report or another file defined within the RPG program).

External Programs Called

The OCL program explicitly calls the following external program: 1. BB9564: - Loaded and executed with the LOAD and RUN commands, this program performs the core processing logic using the NEWPROD and PRCTUM files.

Tables (Files) Used

The program interacts with the following files: 1. Input Files: - NEWPROD (labeled ?9?NWPROD): New product or pricing file, likely containing pricing data generated by previous programs (e.g., BB9563). - PRCTUM (labeled ?9?PRCTUM): Customer master file, containing customer numbers, company numbers, product codes, container codes, and unit of measure.

Summary

The BB9564.ocl36 program is a simple OCL script that loads and executes the BB9564 program as part of the rack pricing update process. It specifies two input files: NEWPROD (new pricing data) and PRCTUM (customer master data), both accessed in shared mode. The program is called conditionally from the main OCL (BB956P.ocl36) when SWITCH2 is set to 1. The only external program called is BB9564, and the files used are NEWPROD and PRCTUM. The specific processing logic (e.g., updating PRCTUM or generating reports) is handled by the BB9564 program, which is not detailed in the OCL.
