FI-alternative reconciliation accounts in MIRO

One of requirements often articulated by users is a need to post of payables from one business partner onto various general ledger accounts (reconciliation accounts). It comes from the Balance Sheet structure that requires to show various liabilities separately (e.g. investment payables are shown separately from trade or public payables)
SAP gives possibility to use special GL indicators and/or alternative reconciliation accounts to meet above requirement. Special GL transactions have some limitations (e.g. payment term cannot be used), and that is why alternative reconciliation accounts are very often chosen by implementation team.
Configuration of alternative reconciliation accounts in FI (Fig1) allows user to change reconciliation account while posting payable or receivable – in order to post for example investment liability, that must be shown separately from regular trade payable.

Manual change of reconciliation account is possible in FI transactions (e.g. F-02, F-43, FB01) and in FI ENJOY transactions (e.g. FV60, FB60, FB65 or FB70) – Fig.2:

But, when we want to post or park an invoice in reference to logistic purchase order (MIRO or MIR7 t-codes), standard SAP solution does not allow to change reconciliation account even though they are configured (Fig.3). GL account field is not editable:

Possible solution in this case – to open GL account field for change in MIRO and MIR7 is activation of enterprise business function FIN_LOC_CI_14 (FI, LO, Localization Topics for Russia 2). This extension is prepared by SAP in order to meet some business requirements of Russian companies and it includes various solutions (e.g. reports) specific for Russia, but it activates also functionality of posting with alternative reconciliation accounts for logistic invoice verification t-codes (MIRO, MIR7, MIRA)
Detailed documentation of this business extension is published by SAP on following www site:

Extension can be activated in SWF5 transaction (Fig.4) on development environment (and saved in transport request in order to transfer it on test and productive environments). It should be activated, of course, after analysis of its impact on existing functionalities and solutions. My experience does not show any negative impact on Polish company codes. But one must be aware, that activation of this extension is not reversible!

After activation of the extension, user will be able to change GL reconciliation account during posting/parking of invoices in MIRO/MIR7 (Fig.5).
