I propose that in the P&L budget plan, you should use the template file has been sent by me to you.
For some of the columns. I have more details as follows.
1. Cost center: The cost center to plan budget cost.
2. Source CCA : Sender Cost center from allocation and used in Internal order(IO by department) Plan.
In template you can revise Account code /committment and add formula in sum total.
In the next step, I can run macros from this template to create text file for upload.
