How to differentiate local and global variables/filters in BW BEx

Hi,

I have created BEx Query, it's contain one global variable/filter and 4 variables of type customer Exit.

I written code for customer Exit variables and the value for variable is also populating but the data is not displaying as per customer exit variables.

Explanation:

Suppose if i pass value to global filter variable (cal year/month) = 201504 the value for customer exit here month is 4 so it is 2nd Quarter so i need to display data for total 2nd Quarter i.e from month 4 Th to 6th .

so the customer variable of type Interval/range ...value is 201504 to 201506 this value is populating but in the restriction key figure data is not displaying .

Here problem is due to Global variable filter the local customer exit variable values data is not displaying in the report.

Please help me ,Thanks in Advance.
