Functional Overview
Its needed to enable a monitor that is able so display the invoices selected in the IHB and the ones that not in case its needed to take action.
This will require a FIORI app to access by business.
Scope and Objectives
The project involves the implementation of a factoring solution within In-House Bank (IHB) using the S/4 Hana FI/IHB module. This system is designed to handle transfer of AP/AR items that are relevant for factoring, to the IHB center for further collection/payable management.
This enhancement covers the monitor to review the integrated items and bring the capacity to integrate new ones.

Design Rationale
Functional Requirements
Factoring Monitor Report configuration and usage must adhere to SAP S/4HANA standard reporting principles and enterprise value policies. Access to the report and related invoice actions is to be governed strictly by role-based security authorization profiles.
Report selection screen parameters must allow input of single, range or multiple values for all key fields (company code, posting date, fiscal year, document type, and invoice document number) based on standard SAP selection method protocols.
Any invoice flagged or de-flagged for factoring must trigger real-time updates to Payment Block Key, House Bank and Account ID fields .
Fiori capabilities similar to List Report output grid must comply with usability standards by providing authorized users the ability to sort, filter, sum, add/remove columns, and export data in standard SAP-supported formats; navigation to source FI, MM, or SD document screens (e.g., Display Journal Entries - FB03, Display Billing Documents - VF03, Display Supplier Invoice - MIR4) must be enabled via configured SAP API services or classic transaction links.
Key functionalities include navigational access from reference document links to underlying FI, SD, or MM invoice transactions, supporting detailed examination and audit trails.

Data Source Considerations
The main tables to retrieve the information are:
- Finance information : ACDOCA (or BSEG, BKPF, FAGLFLEXA,FAGLFLEXT… )
- IHB Contract : /PF1/DB_ORDER ( from Clearing area onwards from the previous list )
- Payment Information : BNK_BATCH_ITEM / BNK_BATCH_HEADER / REGUHM/REGUT / FEBEP

Selection Screen Enhancement
The report should have a selection screen with the following fields :
| Field Name | Description | Select: | Data Type/Length | Default Value/ Validation rule/ Value Help | Selection Logic |
|---|---|---|---|---|---|
BUKRS | Company code | Select-options | CHAR(4) | Mandatory Field | |
KUNNR | Customer Number : Customer account number for receivables postings | Select-options | CHAR(10) | ||
LIFNR | Vendor Number: Account number of vendor or creditor | Select-options | CHAR(10) | ||
| BUDAT | Posting Date: Date when the document was posted to SAP. | Select-option | DATS (8) | Mandatory Field | |
GJAHR | Fiscal year | Select-options | NUMC(4) | Mandatory Field | |
| Document Type (BLART) | Type of accounting document (invoice, payment, etc.) | Select-option | |||
| BELNR for FI, billing document number for SD | Invoice document number | Select-option |
Processing Logic
The main tables to retrieve the information are:
- Finance information : ACDOCA (or BSEG, BKPF, PAYR, REGUT, FAGLFLEXA,FAGLFLEXT… )
- IHB Contract : /PF1/DB_ORDER ( from Clearing area onwards from the previous list )
- Payment Information : BNK_BATCH_ITEM / BNK_BATCH_HEADER / REGUHM/REGUT / FEBEP
Its expected to use API to retrieve the information if possible:
- Display Journal Entries(for FI accounting documents) : CDS I_JournalEntryItem/I_AccountingDocumentJournal
- Display Billing Documents (for SD invoices) : CDS I_JournalEntryItem/I_AccountingDocumentJournal
- Display Supplier Invoice (for MM vendor invoices) : CDS I_JournalEntryItem/I_AccountingDocumentJournal
- ...
| Display the output of the report : | The Output of the report should be able to share the following information: Finance Information ( original invoice and header one )
IHB Contract :
Payment information: From the header document in case of payable:
In case of receivable from the bank reconciliation:
Finance information link to IHB Contract The header information - FI document : BUKRS (Company Code )/ BELNR (Document Number) / GJAHR (Fiscal Year) ( ie: 1010/0123456789/2026) will be stored in Reference field of the IHB contract BNK_BATCH_HEADER - SND_INT_REF. This is the Payment reference text ( CHAR35 ) Finance information link to Payment information: From the header invoice you can find the subsidiary invoice in the BKTXT . This field is stored in the BSEG table. You can access using the FI header information from the previous point in the BSEG and get the SGTXT
Primary Linking Fields from PAYR and REGUT are : LAUFI Payment Run , LAUFD Payment Run , BUKRS Company & LIFNR Vendor Number
Primary Linking Field is GUID
Payment Run ID (LAUFI + LAUFD): Links F110 payment runs ( REGUV, REGUP or REGUH )to BCM thru BNK_BATCH_HEADER :
Finance information link to Reconciliation: From the invoice ( BESEG , BKPF ,ACDOCA ) & Reconciliation ( FEBEP, FEBKO ) it will use the company code ( BUKRS , accounting document number ( BELNR ) , Fiscal Year GJAHR and line item number ( BUZEI) It should be available List report features to add / remove fields , sort , sum/semisum, sort, filter, … |
| Select / Deselect invoices for Factoring | When I display the information, I should be able to select and deselect the relevant invoices for Factoring (selection flag with multiple selection or all should be available and a button to execute the action). This should happen to be updating the invoice ( like FB02 ) the fields Payment Block Key ( ZLSPR ) and House Bank (HBKID) . In case of select it should be flagged Block Key ( ZLSPR ) and it should be populated HKID with IHB1value Technically it can be used the RAP action Post I_JournalEntryItem to update Payment Block Key ( ZLSPR ) and I_JournalEntryTP to update House Bank (HKID) . In case of deselect , beyond removing values from Block Key ( ZLSPR ) and House Bank (HBKID). It should be verified that the Factoring contract is created ( header information - FI document : BUKRS (Company Code )/ BELNR (Document Number) / GJAHR (Fiscal Year) is stored in Reference field of any IHB contract BNK_BATCH_HEADER - SND_INT_REF ) In case factoring contract is created reversal program should be called as well to reverse the factoring contract (ERP-958 IHB Factoring - Reversal program ).

Volumetrics
This volume is estimated to be approx: 10000
Performance Considerations
In case of performance issues due to large number of information to be processed it should be raised the message to restrict the selection parameters and stop the execution.
