OIC on Concurrent Capacity: entitled ba sa RATA?

I want to ask for legal opinion regarding my designation as OIC municipal assessor in a concurrent capacity. My original position is from the Provincial Assessor’s Office holding SG 22 position. In my designation order, I will report to the municipal assessor’s office twice a week but I will still maintain my daily time record at the Provincial Assessor’s Office. Is it allowed to receive

RATA from the municipal government using my DTR in the province? Aside from RATA, what other remuneration i’m entitled to claim? Thank you.
