SAP Note 17539 - Runtime error when deleting transaction data

Symptom:

You delete transaction data using Report SAPF020. Runtime error "CONNE_IMPORT_WRONG_STRUCTURE" occurs.

Other terms

Program "SAPF020", Form "READ_RFDT",
Exception "CX_SY_IMPORT_MISMATCH_ERROR",
Error when importing object "T_BKPF".

Reason and Prerequisites

With the new Release, the structure of held documents in the index file "RFDT" has been changed and they have not yet been appropriately converted.

Solution
Before holding new documents or processing held documents, the documents previously held have to be converted.

Conversion of the held documents is carried out by Report "RFTMPBLU". In case of a large data volume (more than several hundred held documents), the report should be scheduled as batch job.

In general, conversion of held documents is supported for documents entered in Release 1.3A or later.

A conversion of older held documents is impossible. You have to delete those documents using Report "RFTMPBLD". Afterwards, run Report "RFTMPBLU" to activate version management for held documents.

If only small data sets need to be converted or deleted, you can carry out the action in another window and continue the current processing after finishing the action.
