Summary :
Transaction GD12 in SAP faces a runtime error when navigating to line items due to a missing correspondence of the field "FISCYEARPER" within the work area. This discrepancy triggers errors related to dynamic SQL semantics in classes such as CL_FINS_ACDOC_SELECT. To address this program error, SAP suggests implementing a correction through the SAP Note Assistant, preferable ahead of the next Support Package to prevent further disruptions.
