Derivation of Cost Center name from Profit Center name

Hi Experts,

We have a requirement to derive our Cost Center name from the Profit Center, that we add in the Profit Center field in the Cost Center, when we create the cost center.

Thus in our instance the Profit Center number is exactly the same as the Cost Center number, except that the profit Center number will start with P and the Cost Center number will start with C.

I am able to derive the Person responsible field in the Cost Center from the Person responsible field in the Profit Center in this way, using CCTR and PCTR in BRF+  rule,when I add both PCTR and CCTR in my derivation rule, but not sure in which entity I will find the Profit Center name.

The specific fields I am looking for in the Profit and Cost center is TXTMI and TXTSH.

Can you provide any suggestions

Your feedback will be highly appreciated.

Thanks and best regards
