Dear Ravi,
Please do the following:
1. First check in Extractor Checker (RSA3) whether data is coming or not on ECC side for the data source w.r.t the 2 fields which you mentioned.
2. If the data is not coming then you need to write a look up in CMOD Customer Exit for that data source. Again check in RSA3. If data comes in RSA3, it will 100% come in SAP BW.
