query rule

In the "Value" field, you need to remove the double quotes and add ri! instead. 
What you have done right now is you are comparing an Integer field (groupCif_int) with a string ("liabilityNumber_int"). So instead of "liabilityNumber_int" it should be ri!liabilityNumber_int

i have tried with that also

when i given ri it is not filtering all data it is giving

so can you please let me know  how can i write ER for this query

You have exchanged the CIF and liability number fields. Please check..
Rest, the code looks fine and should work. Can you also include the values that you are passing in your RI in the screenshot?

In the picture, you enter the data into groupCIF_int variable but you are not using it anywhere. 

can you please look into this query and let me know

what is the datatype for GCIF and Liability_Number?

all are integer - gcif, cif, liability_number

a!queryLogicalExpression(
operator: "AND",
filters: {
a!queryFilter(
field: "GCIF",
operator: "=",
value: ri!gcif
),
a!queryFilter(
field: "LIABILITY_NUMBER",
operator: "=",
value: ri!liabilityNumber
),
a!queryFilter(
field: "CIF_TYPE",
operator: "=",
value:"Parent"
)
}
)  

please replace your code with the above one and add two rule input variables 1) gcif number(integer) 2) liabilityNumber number(integer). I am not sure why you took GCIF 2 times in where conditions.

I have taken a look and that is what I am suggesting. 
You have configured it incorrectly. Please take a look the screenshots above and try the suggested approach. 

this is how i get data from that query

so in this data i'll give one gcif data and will get only that row

this is what i required from ER

so i have used 2 gicfs

and this will give me all the rows in this i have to filter it 

in the screenshot, GCIF,Liability_Number and CIF is same for all. Then please use the below expression for the querylogicalExpression. 

Note: you have to change the field name(GCIF, CIF_TYPE) in the code. for the please refer your cdt. Rule input GCIF is of integer type.

a!queryLogicalExpression(
operator: "AND",
filters: {
a!queryFilter(
field: "GCIF",
operator: "=",
value: ri!gcif
),
a!queryFilter(
field: "CIF_TYPE",
operator: "=",
value:"Parent"
)
}
)

in the screenshot, GCIF,Liability_Number and CIF is same for all. Then please use the below expression for the querylogicalExpression. 

Note: you have to change the field name(GCIF, CIF_TYPE) in the code. for the please refer your cdt. Rule input GCIF is of integer type.

a!queryLogicalExpression(
operator: "AND",
filters: {
a!queryFilter(
field: "GCIF",
operator: "=",
value: ri!gcif
),
a!queryFilter(
field: "CIF_TYPE",
operator: "=",
value:"Parent"
)
}
)

For reference: 

even  i have checked this also.. this give wrong data 

if i don't apply the filters like GCIF=LIBAILITY and LIABILITY=CIF filter there might be chances of LIABILITY value will have different 

for ex when i apply  GCIF=LIBAILITY and LIABILITY=CIF filter then output will be 

GCIF=102646 and LIABILITY=102646 and CIF=102646

when i don't apply  GCIF=LIBAILITY and LIABILITY=CIF this filter and apply only  GCIF=CIF then output will be 

GCIF=102646 and LIABILITY=735838 and CIF=102646

in this case how to overcome 

Then you can give 3 input and the filters for the same.

I can't really help with this.

When I approach stuff I have a hard time understanding, I try to do small steps, test and validate each step and try to understand what is going on.

Exactly. You need to implement a code logically and also need to understand how to deal with that code.
