Hello!
We use attributeS in order to modify/add values to our fields in our request. Bellow i'll attach an attribute_profile, in csv format, that will change the value of Cell_ID with, for example, "ID1" only if the Account of the request is 1001(this is how we use filters).
````
#Tenant,ID,Context,FilterIDs,ActivationInterval,AttributeFilterIDs,Path,Type,Value,Blocker,Weight
cgrates.org,ATTR_ACNT_1001,*any,*string:~*req.Account:1001,,,*req.Cell_ID,*constant,ID1
,false,10
````
You can populate CDRs through EEs subsystem that can export the CDR containing the fields that you want.
So in order to complete your CDRs table you could add a field in configuration having this format:
{"tag": "Cell_Name", "path": "*exp.Cell_Name", "type": "*variable", "value": "~*req.Cell_Name", "mandatory": true},
Thanks,
Adrian
