Summary :
The SAP function module CONVERT_BANK_ACCOUNT_NUM_LONG is designed to split bank account numbers exceeding 18 digits into several fields to comply with previously issued SAP Notes 96624 and 115002 for compatibility within the R/3 system. Issues arise when the bank country code in the customizing setting does not match the ISO code, as seen with Polish codes 'PLO' vs 'PL'. This stems from the module's failure to convert SAP country codes to ISO codes before querying the bank country. Resolutions for this error are available in standard system updates starting from Release 4.6C and service packages for Releases 4.5B and 4.6B. Workarounds for earlier releases precede these versions.
