What T-Code is employed to correct GL master data affecting ICMR?

• A. FB02 (Change FI Document)
• B. F2543 (Manage Reconciliation Cases)
• C. FS00 (GL Master)
• D. OBY6

Answer: (C)

The transaction code FS00 is used for managing General Ledger (GL) master data in SAP. When it comes to correcting GL master data that impacts the Intercompany Matching and Reconciliation (ICMR) process, this T-Code is the most relevant. It allows users to access and modify the GL account information directly, ensuring that any inaccuracies or required updates in the master data are addressed immediately.

In the context of intercompany transactions, accurate GL master data is crucial since it directly influences the reporting and reconciliation processes between different company codes. Any discrepancies in master data could lead to misaligned financial records, which is why FS00 is specifically designated for this purpose—enabling corrections to be made accurately and swiftly.

Additionally, other options pertain to different functionalities. For instance, FB02 is utilized for changing FI documents, which does not specifically target GL master data. F2543 relates to managing reconciliation cases but does not assist in altering the core GL data itself. OBY6 is used for managing company code settings, leaving it outside the focus of direct GL account corrections. Hence, FS00 is the appropriate choice for correcting GL master data relevant to ICMR.
