The steps to change the COA of a company code that was created by copying another:
- Uncheck company code productive in "Company code global data". This can be found via SPRO -> Financial Accounting -> Financial accounting global settings -> Company Code -> Enter global parameters
- Reset transaction data for company code. T. Code --> OBR1. Enter the company code you want to reset the data for. Other option include resetting relevant CO data, regenerating credit limits and deleting matchcodes. Note: resetting CO data will only work at Controlling area level. It is recommended you do a test run prior to production run. This will display information on data being reset.
- Delete master data. T.Code --> OBR2. This transaction can be used to delete customer, vendor and GL master data. Select the GL Account box and enter the relevant GL account number/ range or leave blank to delete all GL accounts. In deletion depth, select "With general master data in company code" and enter the relevant company code.
- Now the COA can be changed in the company code global data. If you need to copy the GL accounts from another Company code use T. Code OBY2.
