Purpose
This Correction ABAP is only used to correct the settings of the PSAledger 4P, 4Q, 4R and 4S. This is necesary as PSA Rollup is checkingspecific settings of JVA and PSA ledgers. It is necessary to have thesame currency types settings for ledger 4A and 4P, as well as forledger 4Cand 4Q. If those settings are not identical then Rollup willsend an error message and aborts.
In addition this ABAP can be used to block/unblock the Rollup for ledger4Q. So even if ledger 4C is used in JVA, but 4Q and 4S are not requiredfor PSA - ledger 4Q can be blocked for Rollup.
Block Rollup for 4Q - In this case there should be no assignments ofcompany code to ledger 4Q and 4S. If yes this assignments have to bedeleted - see also note 841051. It is also necessary to change sets5J3-PSC-RLDNR-4C and 5J3-PSC-RLDNR-4A-4C has to be changed (ledger 4Cshould be deleted from both sets) - see also note 841051.
Unblock Rollup for 4Q only makes sense if ledger 4Q and 4S are assignedfor the company codes desired and the sets are maintained with ledger4C.

Prerequisites
PSA has been technically installed on this instance.

Selection
COPY JVA LEDGER SETTINGS TO PSA_LEDGERS
Parameter Copy 4A to 4P and 4R - if this flag is marked, then thesettings from 4A (JVA ledger) will be copied to ledger 4P and 4R -which should alswys be treated as group of ledgers (given PSA isinstalled).
Parameter Copy 4C to 4Qand 4S - if this flag is marked, then thesettings from 4C (JVA ledger) will be copied to ledger 4Q and 4S -which should alswys be treated as group of ledgers (given PSA isinstalled). This makes only sense if ledger 4C is correctly set up forJVA.
Parameter Transaction Curr. transfer - if this flag is marked then thetransaction currency key and amounts are transferred via Rollup toledger 4P/Q - only if this is defined for ledger 4A/C in JVA! This isnot really necessary, as PSA does not deal with transaction currencies -it only increases the number of records stored in 4P/Q. Therecommendation is not to transfer transaction currency. This does notinfluence ledger 4R/S, as the PSA calcualtion populates ledger 4R/S in adifferent way (Currencies and quantiities are taken from the PSA masterdata).
Parameter Debit/Credit Indicator transfer - if this flag is marked thenthe Debit/Credit indicator is populated - only if this is defined forledger 4A/C in JVA! This is not necessary, as JVA as well as PSA arealways balancing both records and only the balance is taken into thecalculation. It increased thge number of records stored in 4P/Q ad 4Rand 4S. The recommendation is not to use the Debit/Credit Indicator.
Quantity ffor 4P/Q transfer - if this flag is marked then the unit ofmeasure and quantities are transferred via Rollup to ledger 4P/Q - onlyif this is defined for ledger 4A/C in JVA! This is not reallynecessary, as PSA does not deal with transaction currencies in therollup ledger- it only increases the number of records stored in 4P/Q.This does not influence ledger 4R/S, as the PSA calcualtion populatesledger 4R/S in a different way (Currencies and quantiities are takenfrom the PSA master data).
BLOCK/UNBLOCK LEDGER 4Q FOR ROLLUP
If ledger 4C, Q and S are not used then it is necessary to block Rollupfor ledger 4Q, as otherwise Rollup would send an error message.
The unblock option is just here to reverse an incorrect setting.
UPDATE
Table T881 is only updated if the Update mode is marked.
