Foreign Income Mandatory report filing

Hi everyone,

A client received payment in foreign currency for services offered to an Indian Subsidairy from its Parent company based abroad. the client is also Director of this Indian subsidiary. He doesn't get any other payment  from the Indian Subsidiary. 

Is it mandatory to file any report to RBI / IT Dept for these type of  transaction. Pls confirm. if so pls name them and where can we get the formats??

Thanks.
