Data request on F986110 getting max job number

Good morning,

trying to get from F986110 the maximum job number for a specific user and report. First time i get the result,

{
  "ds_F986110": {
    "output": [
      {
        "groupBy": {
          "F986110.USER": "SCHEDORCH"
        },
        "F986110.JOBNBR_MAX": 553540
      }
    ]
  }
}

from the next iteration i get this output

"ServiceRequest2": {
    "ds_F986110": {
      "output": []
    }
  }

If i sign off the user and log in the data request works for the first time and the next doesn't work. Any suggestion ?
