SAP Note 19800 - Batch input problems in KB11, KB21, KB31 and KB41

Symptom:

Key words : Actual postings, batch input
Programs : SAPMK23A, SAPMK23B
Transactions : KB11 Enter Reposting of Primary Costs
KB41 Enter Reposting of Revenues
KB21 Enter Allocation of Activities
KB31 Enter Statistical Key Figures

Customer-defined batch input programs for the above CO actual posting transactions, that could be executed up to and including Release 2.1, no longer work as of Release 2.2A.
When batch input sessions are processed, the system generates error message 00344 'Batch input data for screen SAPMK23B 1001 does not exist' for example after starting the session.

Cause and prerequisites

As of Release 2.2, the actual posting transactions use a different program (SAPMK23B) than the program used in 2.1 (SAPMK23A).
The flow logic has also changed. In Release 2.1, a dialog box for entering a transaction currency was displayed during the transfer posting of costs and revenues to the initial screen. As of Release 2.2A, this dialog box is no longer processed. Instead, the transaction currency field (RK23A-TWAER) is not ready for input on the following list or detail screen.

Solution
All customer-defined batch input programs which process screen of program SAPMK23A must be converted to the new program SAPMK23B.

Every customer should check whether he can use the SAP standard reports for the data transfer into the actual posting transactions.
It is basically always possible that customer-defined programs, which generate batch input, can no longer be executed after release upgrades because screen names, fields and program flows can change.
With SAP programs, these adaptations would no longer be necessary for the customer.

The standard batch inputs are realized via function modules which you have to call and fill with the required posting data via the corresponding interface structure.
The following function modules are available:
