Update Sap Table

Hello All,

I have to update a field 'RFAREA' in SAP table 'GLPCT' for all entries based on the profit center field 'RPRCTR'. I have a list of profit centers and corresponding functional areas in an excel sheet.

Can you please tell me how to do this? And what are the things I need to consider for modifying this table?

Thanks in Advance,

Anitha
