I have a formula which defines the patient type. a patients patient type is defined by 1- if they are in ICU, 2- if they have specific type of line. 3- if they do hot have a cl or in ICU.
the following formula is used to get the patient type

IF {Command.DEPARTMENT_ID} IN [2133009,4313023,4313015,4313016,4314007,4314009,4314027,5119219,5119221,5115578,73,5115579,5119222,5123216,
5133207,5119223,5101202,5133026,5119220,5120202,5119218,5119235] THEN 'CHG'
ELSE
IF NOT ISNULL({Command.IP_LDA_ID_A}) THEN Minimum ({Command.PATIENT_TYPE}, {Command.Y_MRN})
ELSE
{Command.RM_PATIENT_TYPE}

the above formula is used in a compliance formula below

IF {Command.BATH_STATUS}='NOT DOCUMENTED' THEN 'NO'
else
IF {@PATIENT TYPE}='STANDARD' AND {Command.BATH_STATUS}='WASHED / GIVEN'
AND ISNULL({Command.STANDARD_BATH})THEN 'NO'
ELSE
IF {Command.BATH_STATUS}='Refused' THEN 'N/A'
ELSE
IF {Command.MEAS_VALUE} LIKE '*Refuse*' THEN 'N/A'
ELSE
IF {Command.MEAS_VALUE} LIKE '*Contrain*' THEN 'N/A'
ELSE
IF {Command.BATH_STATUS}='NOT DOCUMENTED' THEN 'NO'
ELSE
IF {Command.BATH_STATUS}='NOT GIVEN' THEN 'NO'
ELSE
IF {Command.MEAS_VALUE} LIKE '*Incontinence care*' THEN 'NO'
ELSE
IF {Command.MEAS_VALUE} LIKE '*Independent*' THEN 'YES'
ELSE
IF {Command.MEAS_VALUE} = 'NOT GIVEN' THEN 'NO'
ELSE
IF{@PATIENT TYPE}='STANDARD' AND {Command.BATH_STATUS}='WASHED / GIVEN'
AND {Command.STANDARD_BATH} ='Standard bathing wipes' THEN 'YES'
ELSE
IF{@PATIENT TYPE}='STANDARD' AND {Command.BATH_STATUS}='WASHED / GIVEN' AND NOT ISNULL({Command.STANDARD_BATH})THEN 'YES'
ELSE
IF{@PATIENT TYPE}='STANDARD' AND {Command.BATH_STATUS}='WASHED / GIVEN' AND NOT ISNULL({Command.STANDARD_BATH})
AND NOT ISNULL({Command.CHG})THEN 'YES'
ELSE
IF{@PATIENT TYPE}='STANDARD' AND {Command.BATH_STATUS}='WASHED / GIVEN' AND NOT ISNULL({Command.STANDARD_BATH})
AND ISNULL({Command.CHG})THEN 'YES'
ELSE
IF{@PATIENT TYPE}='CHG' AND {Command.BATH_STATUS}='WASHED / GIVEN' AND NOT ISNULL({Command.STANDARD_BATH})
AND NOT ISNULL({Command.CHG})THEN 'YES'
ELSE
IF{@PATIENT TYPE}='CHG' AND {Command.BATH_STATUS}='WASHED / GIVEN' AND NOT ISNULL({Command.CHG})THEN 'YES'
ELSE
IF{@PATIENT TYPE}='STANDARD' AND {Command.BATH_STATUS}='WASHED / GIVEN' AND ISNULL({Command.STANDARD_BATH}) THEN 'NO'
ELSE
IF{@PATIENT TYPE}='CHG' AND {Command.BATH_STATUS}='WASHED / GIVEN' AND {Command.STANDARD_BATH} ='Standard bathing wipes'
AND ISNULL({Command.CHG}) THEN 'NO'
ELSE
IF{@PATIENT TYPE}='STANDARD' AND {Command.BATH_STATUS}='WASHED / GIVEN'
AND ISNULL({Command.STANDARD_BATH}) THEN 'NO'

i am trying to sort or group on the above formula but i get the following error

GROUP SPECIFIED ON NON RECURRING FIELD.

any idea how to correct this so i can group on it?
