The DEEPSEEKAPPS.PO_DOC_NUMBERING_PKG package in Oracle E-Business Suite (EBS) versions 12.1.1 or 12.2.2 interacts with the EGO_COL_NAME_VALUE_PAIR_TABLE as part of its document numbering logic, particularly when integrating with Oracle Product Lifecycle Management (PLM) modules. Below is a detailed technical analysis of this dependency:

1. Functional Context

The PO_DOC_NUMBERING_PKG package manages document numbering sequences for procurement documents (e.g., POs, Requisitions). Its dependency on EGO_COL_NAME_VALUE_PAIR_TABLE (a PLM structure) arises when:
  • Implementing PLM-controlled numbering schemes for procurement documents
  • Validating document attributes against PLM item master data
  • Enforcing PLM-driven numbering rules during document creation

2. Technical Integration Points

Key integration methods include:

2.1 Data Type Handling

EGO_COL_NAME_VALUE_PAIR_TABLE is used as: 
TYPE ego_col_name_value_pair_table IS TABLE OF ego_col_name_value_pair_rec 
INDEX BY BINARY_INTEGER;
The package uses this PLM-defined collection type when:
  • Processing PLM-extended attributes during document numbering
  • Passing attribute sets between procurement and PLM modules

2.2 API Interactions

Critical procedures like generate_document_number may call PLM APIs that require EGO_COL_NAME_VALUE_PAIR_TABLE parameters when:
  • Checking PLM-based numbering constraints
  • Validating document attributes against PLM item classifications

3. Dependency Scenarios

3.1 Numbering Rule Resolution

When PLM-controlled numbering is active:
  1. The package queries PLM to determine applicable numbering rules
  2. PLM returns rule criteria in EGO_COL_NAME_VALUE_PAIR_TABLE format
  3. Package applies these rules during document creation

3.2 Cross-Module Validation

For documents referencing PLM-managed items:
  • Item attributes are passed as EGO_COL_NAME_VALUE_PAIR_TABLE
  • Numbering rules may vary based on PLM item classifications

4. Impact Analysis

4.1 Customization Considerations

Modifications to PO_DOC_NUMBERING_PKG must:
  • Maintain proper initialization of EGO_COL_NAME_VALUE_PAIR_TABLE variables
  • Handle NULL collection cases when PLM integration is disabled

4.2 Upgrade Implications

Between 12.1.1 and 12.2.2:
  • Structure of EGO_COL_NAME_VALUE_PAIR_TABLE remains consistent
  • New PLM attributes may be introduced requiring package updates

5. Troubleshooting

Common issues include:
  • ORA-06502 errors when incorrectly populating the collection
  • Numbering rule mismatches due to PLM attribute changes
  • Performance degradation when processing large attribute sets
This dependency exemplifies the tight integration between Oracle Procurement and PLM modules in EBS, where document numbering rules can be dynamically controlled based on PLM-managed item attributes and business rules.
